    SubjectRe: [PATCH] Make highly niced processes run only when idle
    I'm not a kernel hacker by any stretch of the imagination but I do
    follow lkml. While SCHED_IDLE would be really nice it seems like this
    topic comes up from time to time there always seems to be a (deadlock)
    catch that keeps it from getting into the main kernel tree. While it
    would be really great if Robert's patch turns out to be the magic bullet
    this time, as a Linux user and SetiAtHome supporter I would be happy
    just to have a "nice -19" that was truly nice. Running setiathome at
    nice -19 on my box and then firing up a processor intensive process at
    normal priority, I find that seti still uses 14% processor according to
    top. I like to run 2 setiathome processes because I get better overall
    throughput that way, but the 2 combined then get ~25% of the processor.
    Not really all that nice. Would it be difficult to make "19" a special
    case that was really, really nice, but not *totally* nice? Avoiding
    deadlock but still following the spirit of SCHED_IDLE?
