           Summary: Creating windows in threads may deadlock

testcase (source + binary - w32)

Creating windows in threads may deadlock at gdi_section and X11DRV_CritSection.
This doesn't seem to happen on win xp. Though I'd expect that it should be
possible to create windows from a thread. Attached is a small test case.

Howto:
- run graphics.exe
- hit the button "start" a couple of times and the deadlock may appear
(sometimes it takes ages to trigger it, sometimes the first hit will make it
happen)

Log:
err:ntdll:RtlpWaitForCriticalSection section 0x688ef580
"../../../git/dlls/winex11.drv/x11drv_main.c: X11DRV_CritSection" wait timed
out in thread 0009, blocked by 002f, retrying (60 sec)
err:ntdll:RtlpWaitForCriticalSection section 0x68e2d960
"../../../git/dlls/gdi32/gdiobj.c: gdi_section" wait timed out in thread 002f,
blocked by 0009, retrying (60 sec)
