Erik has asked me to try to make progress on this while he's on
vacation, rather than possibly letting it sit until he gets back.
(This is just one of a large stack of patches Erik has prepared toward
the GC access interface that he's been talking about for a while.
Providing a solid base for that work is the underlying goal for
changing atomics.)  I'm getting caught up on the discussion, and
looking at Erik's most recent proposal.  I should have something more
concrete soon, possibly just agreeing with Erik's recent ideas,
possibly some alternative.  I'm also open to suggestions…
