    SubjectNice 19 process still gets some CPU
    Given how much I've read here about schedulers, I should probably be 
    able to answer this question myself, but I just thought I might talk to
    the experts.

    I'm running SETI@Home, and it has a nice value of 19. Everything else,
    for the most part, is at zero.

    I'm running kernel gentoo-dev-sources-2.6.7-r6 (I believe).

    When I'm not running SETI@Home, compiler threads (emerge of a package,
    kernel compile, etc.) get 100% CPU. When I AM running SETI@Home,
    SETI@Home still manages to get between 5% and 10% CPU.

    I would expect that nice 0 processes should get SO MUCH more than nice
    19 processes that the nice 19 process would practically starve (and in
    the case of a nice 19 process, I think starvation by nice 0 processes is
    just fine), but it looks like it's not starving.

    Why is that?
