This patch fixes the throttling mechanism. It was broken
in 3.2.0. Events were not being unthrottled. The unthrottling
mechanism required that events be checked at each timer tick.

This patch solves this problem and also separates:
- unthrottling
- multiplexing
- frequency-mode period adjustments

Thanks!

Should this be Cc'ed to stable@?
