- (dtucker) [channels.c configure.ac serverloop.c] Bug #1102: Around AIX
4.3.3 ML3 or so, the AIX pty layer starting passing zero-length writes
on the pty slave as zero-length reads on the pty master, which sshd
interprets as the descriptor closing. Since most things don't do zero
length writes this rarely matters, but occasionally it happens, and when
it does the SSH pty session appears to hang, so we add a special case for
this condition. ok djm@
