I'm not quite sure, but my understanding was that this expression does
answer this question:

(fd_info[p->infd].flags & FILE_CONNECT) == 0

Or am I wrong?

See also patch in the previous message.  If we decide to go this
direction, then I think we should also inhibit the first call to
gnutls_try_handshake from gnutls_boot, for async sockets.  This call is
currently implicit and will probably fail (return with EAGAIN) in all
practical cases.
