Answer 1

With the literally hundreds (thousands?) of threads a PC runs today, the only way I can think to even come close would be to poll CPU usage as fast as possible, and if the usage% was below where it should be on the curve, to fire off a short method that just churns numbers. That will at least bring the typical low usage UP where needed, but I can't think of a good way to LOWER it without somehow taking control of other threads, and doing something such as forcing thier priority lower.
