    Btw, I realize that you can't give good oprofiles for the user-mode
    components, but a kernel profile with even just single "time spent in user
    mode" datapoint would be good, since a kernel scheduling problem might
    just make caches work worse, and so the biggest negative might be visible
    in the amount of time we spend in user mode due to more cache misses..
