Yeah, some sort of "multi-thread-aware GC", which either allows
objects to be moved between threads (not so simple of course,
e.g. with deep-vs-shallow, strings, etc), or even better allows one to
just _share_ objects directly between threads, does seem the holy
grail.

Hmm, surely the interaction of GC and multi-threading must have
received a lot of research attention by now...
