    remote gdb does that fine.

    I've never seen a nested task gate on Linux...

    Given. Priority inversion does not seem to be a big problem in Linux though
    (kernel threads usually run at the same priority, with the only higher
    priority being interrupts/bhs). Also the sleep locking seems to be generally
    simple enough that it is not a problem for user processes.
