    I hope that it creates something like the following pseudo code, using
    some SPARC to show the membars. If not then on my stack_mutex fun thing
    I posted earlier, Subject "A fun mutex, part II...", well, they would be
    in the wrong places.

    Afaict, acq_rel does that and works fine. But, it makes me think of the
    name. Should it be rel_acq? ;^)
