... looks like the reason for freezing, is a concurrent waiting in
xcb_wait_for_special_event(..).

While the main thread is waiting for present related events, another thread is
consuming this events (because he was the first one entering the wait) and the
main thread is waiting for ever (freeze).

I will attach the debug log for some frames before the freeze.



@Thomas, 
if my frame rate is lower (FPS < Monitor Sync, because of to much debug
output), i don't get any freezes. Could this be the reason why you can't
reproduce the freezes with svga-stack?
