-The lookup function implementation in
-nss/nss_files/files-XXX.c:DB_LOOKUP has code to prevent that.  It is

-
-keep_stream is initialized from the stayopen flag in internal_setent.
-internal_setent is called from the set*ent implementation as:
-
-  status = internal_setent (stayopen);
-
-However, for non-host database, this flag is always 0, per the
-STAYOPEN magic in nss/getXXent_r.c.
-
-Thus, the fix is this:
-
--  status = internal_setent (stayopen);
-+  status = internal_setent (1);
-
-This is not a behavioral change even for the hosts database (where the
-application can specify the stayopen flag) because with a call to
-sethostent(0), the file handle is still not closed in the
-implementation of gethostent.

-+     between TRYAGAIN (recoverable) and TRYAGAIN' (not-recoverable).

-+     and send_vc to see response can arrive in any order, particlarly
-+     for UDP). However, we expect it holds roughly enough of the time
-+     that this code works, but certainly needs to be fixed to make this

-+     [1] If the first response is a success we return success.
-+         This ignores the state of the second answer and in fact
-+         incorrectly sets errno and h_errno to that of the second
-+	 answer.  However because the response is a success we ignore
-+	 *errnop and *h_errnop (though that means you touched errno on
-+         success).  We are being conservative here and returning the
-+         likely IPv4 response in the first answer as a success.
-+
-+     [2] If the first response is a recoverable TRYAGAIN we return
-+	 that instead of looking at the second response.  The
-+	 expectation here is that we have failed to get an IPv4 response
-+	 and should retry both queries.
-+
-+     [3] If the first response was not a SUCCESS and the second
-+	 response is not NOTFOUND (had a SUCCESS, need to TRYAGAIN,
-+	 or failed entirely e.g. TRYAGAIN' and UNAVAIL) then use the
-+	 result from the second response, otherwise the first responses
-+	 status is used.  Again we have some odd side-effects when the
-+	 second response is NOTFOUND because we overwrite *errnop and
-+	 *h_errnop that means that a first answer of NOTFOUND might see
-+	 its *errnop and *h_errnop values altered.  Whether it matters
-+	 in practice that a first response NOTFOUND has the wrong
-+	 *errnop and *h_errnop is undecided.
-+
-+     [4] If the first response is UNAVAIL we return that instead of
-+	 looking at the second response.  The expectation here is that
-+	 it will have failed similarly e.g. configuration failure.
-+
-+     [5] Testing this code is complicated by the fact that truncated
-+	 second response buffers might be returned as SUCCESS if the
-+	 first answer is a SUCCESS.  To fix this we add symmetry to
-+	 TRYAGAIN with the second response.  If the second response
-+	 is a recoverable error we now return TRYAGIN even if the first
-+	 response was SUCCESS.  */

-+
-+   Please also note that for TCP we send both queries over the same
-+   socket one after another.  This technically violates best practice
-+   since the server is allowed to read the first query, respond, and
-+   then close the socket (to service another client).  If the server
-+   does this, then the remaining second query in the socket data buffer
-+   will cause the server to send the client an RST which will arrive
-+   asynchronously and the client's OS will likely tear down the socket
-+   receive buffer resulting in a potentially short read and lost
-+   response data.  This will force the client to retry the query again,
-+   and this process may repeat until all servers and connection resets
-+   are exhausted and then the query will fail.  It's not known if this
-+   happens with any frequency in real DNS server implementations.  This
-+   implementation should be corrected to use two sockets by default for
-+   parallel queries.
-+
-+   The query stored in BUF of BUFLEN length is sent first followed by
-+   the query stored in BUF2 of BUFLEN2 length.  Queries are sent
-+   serially on the same socket.
-+
-+   Answers to the query are stored firstly in *ANSP up to a max of
-+   *ANSSIZP bytes.  If more than *ANSSIZP bytes are needed and ANSCP
-+   is non-NULL (to indicate that modifying the answer buffer is allowed)
-+   then malloc is used to allocate a new response buffer and ANSCP and
-+   ANSP will both point to the new buffer.  If more than *ANSSIZP bytes
-+   are needed but ANSCP is NULL, then as much of the response as
-+   possible is read into the buffer, but the results will be truncated.
-+   When truncation happens because of a small answer buffer the DNS
-+   packets header feild TC will bet set to 1, indicating a truncated
-+   message and the rest of the socket data will be read and discarded.
-+
-+   Answers to the query are stored secondly in *ANSP2 up to a max of
-+   *ANSSIZP2 bytes, with the actual response length stored in
-+   *RESPLEN2.  If more than *ANSSIZP bytes are needed and ANSP2
-+   is non-NULL (required for a second query) then malloc is used to
-+   allocate a new response buffer, *ANSSIZP2 is set to the new buffer
-+   size and *ANSP2_MALLOCED is set to 1.
-+
-+   The ANSP2_MALLOCED argument will eventually be removed as the
-+   change in buffer pointer can be used to detect the buffer has
-+   changed and that the caller should use free on the new buffer.
-+
-+   Note that the answers may arrive in any order from the server and
-+   therefore the first and second answer buffers may not correspond to
-+   the first and second queries.
-+
-+   It is not supported to call this function with a non-NULL ANSP2
-+   but a NULL ANSCP.  Put another way, you can call send_vc with a
-+   single unmodifiable buffer or two modifiable buffers, but no other
-+   combination is supported.
-+
-+   It is the caller's responsibility to free the malloc allocated
-+   buffers by detecting that the pointers have changed from their
-+   original values i.e. *ANSCP or *ANSP2 has changed.
-+
-+   If errors are encountered then *TERRNO is set to an appropriate
-+   errno value and a zero result is returned for a recoverable error,
-+   and a less-than zero result is returned for a non-recoverable error.
-+
-+   If no errors are encountered then *TERRNO is left unmodified and
-+   a the length of the first response in bytes is returned.  */
