    This has been updated for 2.4.1-pre3

    - Fixed latency problems with some /proc files and forking
    when many files are open.

    - Fixed the tcp-minisocks thing.

    - The patch now works properly on SMP.

    If a wakeup is directed to a SCHED_FIFO or SCHED_RR
    task then we request a reschedule on *all* non-idle
    CPUs.

    This causes any CPU which is holding a long-lived
    spinlock to bale out, allowing the target CPU to
    acquire the spinlock and then reschedule normally.

    Bit of a hack, but it works very well and there
    is no impact on the system unless there are
    non-SCHED_OTHER tasks running.

    Five lines of code :)
