The patch didn't come through the mail, and I'm in an internetless cafe,
so I can't see it now -- but it seems a somewhat sane hack.

Did you see Dybvig's paper about underflow and overflow handlers? That
does solve this problem in a more robust way, including allowing for
stack extension instead of thrown exceptions. Of course that's probably
a larger project.
