Well, I think that MPS is bring-your-own-thread concurrent.  I'm not
sure the current MPS can usefully be concurrent, because of the thread
suspension thing, but we can run it in another thread if we want to.

(If it turns out that using a separate thread isn't an advantage, we
should look at reducing the size of our roots (or protecting them)
rather than giving up on the idea entirely.  As long as other threads
freely move references to and from global roots, detecting unreachable
objects is hard.)
