I'm curious about this because the question of error handling keeps
popping up and I'm wondering whether our current solution is good
enough.  (With a strong suspicion that it isn't.)

One thing I'm not sure I understand is why you want (or perhaps need)
to do this lazy-catch in C rather than in Scheme, since it would be
much easier in Scheme.  Can you explain?
