I would like to be able to use exceptions in as transparent a method
as possible. But if that solution causes ugly code with bad 
performance, it should be avoided. I have the following questions.

1. What would a gtk_signal_exception_cleanup function do? I am not
   sure I understand exactly what we need to fix, or what method
   is used to fix it.

2. Where would it go (gtk-- code or user code)? 

3. What would it do to the performance of programs that don't
   use exceptions?

I also copied this to the gtkmm list. I thought we should talk
about it there.

Todd.
