Toward better CPU idle-time predictions

If you delay the processing of a keyboard event with 50 ms you suddenly have a 3 frame latency at 60 fps, and a 6 frame latency at the desired 120 fps that is needed for things like the Occulus rift.

And trust me, you notice it when you get a 3 frame higher input latency than before. It's a very noticeable thing when you're in a game.
