[sr #107660] gnutls update to 2.12 branch breaks programs in ARCH and Debian squeeze

[Nikos Mavrogiannopoulos]

Follow-up Comment #10, sr #107660 (project gnutls):

Note that select() is used to check for data in the kernel networking buffers.
This will not change. What changed (in 3.0.0) is that select() cannot be used
any more to check for data in the GnuTLS read buffers.

GnuTLS doesn't hold any write buffers, i.e., every data given to
gnutls_record_send() are immediately forwarded to underlying transport layer.
Thus, you don't need any equivalent to gnutls_record_check_pending() to know
whether writing to the socket would block. It solely depends on the transport
layer (i.e. send()).
