Attaching commented log from wineserver when the issue appears.

As you see we have two socket entries, and when processing the second entry the
first entry is altered, and poll_socket is left with flags != 0 which should
never happen. This will cause the assert later during async_poll_timeout.
Reason is the event we get in sock_poll_event when processing the second entry.
