Can you please try this version? It tries harder to correct any
imbalance... hopefully not too hard. In case you didn't notice, you need
to let your exploits run for a bit before the throttling will take
effect. I intentionally start tasks off at 0 cpu usage, so it takes a bit
to come up to it's real usage.
