The code you have in USE_KEY_BUFFERING is not key buffering, it is a
way to prune events that enter the queue too quickly. If f.ex. I keep
a key pressed, I expcet the insertion of the key to stop the moment I
release it. Same for scrolling, I expect the scroll motion to stop the
moment I release the PgDn key.
So there seem to have been some misunderstandings here.
