A new idea just occurred to me while answering Richard's question.
We can use mostly copying when the size of the stack is small, and switch
to fake copying when the size of the stack is large.  This way, you can
have the cake and eat it too!

I suspect that this idea will be incorporated into MM eventually, and
reference counting will be eliminated all together.
