    In any case, if a process is sleeping in-kernel, I expect that either
    it's an
    interruptible sleep or a guaranteed-short sleep. If it's neither, it's
    a bug. If
    I kick out an ethernet and it makes "ping" hang in "D", that's bad. I
    think
    that eventually _all_ kernel sleeps on the behalf of user-space
    processes
    will become interruptible.

    Cheers,
