 One minor complication is that in the single-threaded case, everything will
 presumably have to continue working as it does now.
 
 The alternative would be to require an explicit client call to run
 finalizers.  That's probably closer to correct, but I suspect it would break
 a lot more existing code.  Single-threaded finalization just doesn't work
 well.

 That would be perfect.  We'll have the finalizer thread wait on a
 condition variable, and we'll have the callback notify it.
