I timed a pathological benchmark from hell I've been playing with lately.
Three consecutive runs following a fresh boot. Time is in seconds:

2.4.21 821 21 25
2.6.0-test3-mm1 724 946 896
2.6.0-test3-mm1-nick 905 987 997

Runtime with ideal scheduling: < 2 seconds (we're thrashing).

If anybody has thrashing test cases closer to the real world, I'd be very
interested to learn about them.
