This simply does not work. It assumes there is only one frame per root window,
which is wrong.
It assumes Emacs will get Unmap events when something obscuring it goes away,
this is wrong (other applications may cover Emacs and the go away).
Any optimization attempt in this area is futile, it will lead to errors for a
very small performance benefit. The time is better spent into doing a proper
double buffer solution.
