Seeing how we use runnable_avg_period for both runnable and running, does it make sense to remove the runnable part of it from the name? Also, 4 byte hole here, not sure we've got anything useful to stuff in it though.

Man, I should go look at Yuyang's rewrite of this all again. I just tried to figure out the decay stuff and my head hurts ;-)
