Hello,

I experienced several gdi/x11 lockups in various windows gui applications with
recent git snapshots.
While trying to verify a bug (http://bugs.winehq.org/show_bug.cgi?id=9724) I
noticed that application is actually quite good for reproducing (instant lockup
on file open/save dialog).
Though it suffers from other bugs unrelated to this one so I filed this issue
as separate bug.

This is a regression, causing gui applications to completely lock up

It should be noted that this commits cause immediate lockup in some
applications - but not all.
It's possible that later commits escalate this problem/behaviour further.
