    SubjectRe: [patch] SCHED_SOFTRR starve-free linux scheduling policy ...

    Yes, that ~works. I couldn't starve root to death as a SCHED_SOFTRR user,
    but the system was very sluggish, with keystrokes taking uncomfortably
    long. I also had some sound skips due to inheritance. If I activate
    xmms's gl visualization under load, it inherits SCHED_SOFTRR, says "oink"
    in a very deep voice, and other xmms threads expire. Maybe tasks shouldn't
    inherit SCHED_SOFTRR?

    While testing, I spotted something pretty strange. It's not specific to
    SCHED_SOFTRR, SCHED_RR causes it too. If I fire up xmms's gl visualization
    with either policy, X stops getting enough sleep credit to stay at a usable
    priority even when cpu usage is low. Fully repeatable weirdness. See
    attached top snapshots.
