    yeah. The biggest item in -ck besides SD is swap-prefetch, but that
    shouldnt have an effect in this case. I _think_ that most of the
    measured difference is due to scheduler details though. Right now my
    estimation is that with the patch i sent to Rob, and with latest
    sched-devel.git, CFS should perform as good or better than SD, even in
    these micro-benchmarks. (but i cannot tell what will happen on Rob's
    machine - so i'm keeping an open mind towards any other fixables :-) I'm
    curious about the next round of numbers (if Rob has time to do them).
