Subject: [PATCH] Optimization

This is much faster. It doesn't create messages, it doesn't post
stuff in a queue, it doesn't delay execution of other messages.
Also, it decouples the timer from the functionality of the Handler
so this can be pulled up in another change to consolidate with
mLastKeyTime or so.
