Oh, yes, that part is fine. The problem is what happens
if thread A stuffs a reference into another object that
lives beyond A's interest in matters. Then another
thread can see an object that still has local ref
counts, even though the owning thread no longer cares
about it and is never going to get rid of those local
refcounts itself. I haven't thought of a non-expensive
way of fixing that yet.
