} Hmm, did you check that this hasn't a bad effect on the cache memory when
} a cpu intensive process has to sleep for short times?
} A /proc/sys interface to tune it would be nice too.

This would also presumably affect the heat production of the CPU -
especially on hot Cyrixs!

Does it spend all the idle time doing this, or just a part??
