hmm..that fits with the "top" report of 50% idle that I've seen.
We've already got a bug report on this, iirc.

Your observation suggest something wrong with either process scheduling
or process accounting.

And I hope CPU0 isn't completely idle, look at /proc/interrupts.
I know interrupt distribution works.

network/IO intensive load - lots of interrupts...hmm.
