Sorry for not using your patch, but there must always be a thread reading from the socket when there is one that writes.

Fix a multi-thread deadlock

This fixes a deadlock which was seen in-the-wild with wine.

It could happen that two threads tried to read from the socket at the same time
and one of the thread got stuck inside of poll()/select().

The fix works by making sure that the writing thread doesn't steal the reading
thread's reply.
