<pre>Sorry for not using your patch, but there must always be a thread reading from
the socket when there is one that writes.
commit 23911a707b8845bff52cd7853fc5d59fb0823cef

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.
