Ok, great!  I'm glad you've already thought about this, because I expect
it's definitely possible to get exception unwinding correct, but maybe
not trivial.

I'm not clear from your reply about the current status of dyninst.git
vs. your research.  Do you mean that Dyninst doesn't handle exceptions
at all right now?  Or that it works barring some bugs (like my test),
and your research is the more elegant technique?

Thanks,
