--- Comment #1 from Filip Pizlo <fpizlo at apple.com> ---
There are two things that definitely need to get done for this to be correct:

1) Separate the SlotVisitor used by the mutator's write barrier from the SlotVisitor used by the collector thread.  It's not super clear if the write barrier should even use a SlotVisitor, but whatever - the MarkStackArray probably has everything we need to efficiently transfer the entire contents of the mutator SlotVisitor into the collector SlotVisitor.

2) We need to stopAllocating/resumeAllocating.  It's tempting to think that this should be done by the mutator, but that's actually just complicating things.  It should be the collector's responsibility, and I think that these methods should be called from stopTheWorld/resumeTheWorld.
