Great!

Do you really think this will make so much difference?
If the issue is avoiding the function call, we could move the test to
the finalizer loop, and this should really save us some cycles.
However, I'm not sure creating new allocation types will save us much,
since the test of which allocation type to use will have to be
performed either at object allocation time or finalization time. I'm
not sure how much moving this test to allocation time would save, in
terms of processing of the finalization list. Maybe it's worth a try,
but I don't expect as much improvement as this first step.
