    Yah, definitely for simple things like this, it will save us a lot
    of work in the future.  And so I have.

    p.s.  I'm pretty sure that the lock prefix costs nothing on a UP system,
    and probably wouldn't be noticed on an SMP system either because the
    write-allocation overhead is already pretty bad.  But I haven't tested
    it.
