    They're used by hazard pointers and RCU both of which are going in.
    Only 20 years from POC to a C++ standard. Time flies.

    :^) Nice.

    Now what about data-dependent load barriers, ala consume? Well, a
    consume that falls back to an acquire is a no go right off the bat
    unless its on an Alpha?
