    Of course, which is why the idea is for the limit to be global, across
    all non-root users. AFAIK, that's what Ingo's original (pre-2.6.12)
    patch did and also what Con Kolivas' SCHED_ISO patch does. That's also
    why I think it would be very hard (if possible at all) to do this in
    user space.
