CATCH and THROW is made to order for this kind of problem.  Put a CATCH
in MAIN and a THROW where you detect the error.

I posted a writeup, including a sample implementation that works on most
systems, a few weeks ago.  If anybody needs a copy, drop me a line and I'll
resend it.  If you can't email to me directly, post a request and I'll
repost the writeup.
