like ex2.err or something. If your routine(s) themselves crash, 
there won't be any more calls to crash routines. That's the end."

Rob, I am glad to see that you are implementing improved exception
handling. I will be happy to get most anything you provide (even
while I have my personal preferences.) So, let me make just two comments.

1. As to filename "ex2.err", use something more mnemonic such as:
 except.err
 cleanup.err
 exclean.err
 exuser.err
or whatever mnemonic you choose.

2. I agree with Parnell about the utility of detailed error data being
passed to the routine. In addition to Parnell's suggestions, I would like
to receive the routine name also, using something like "global", "local"
or "top" or whatever is best for statements not inside defined routines.
