I'm finishing the tutorial I talked about, and when writing the XEvent
part (the last one), I found out that XCopyArea will produce a
NoExpose event. If I sync the output buffer with False (that is to
say, without discarding the events from queue), I can intercept it in
the recursive loop without the need of nextEvent' and asynchronous
Now I'm even more puzzled...
