It really does sound like an obscure corner case. But how about this
semi-real-world example?

        function main ()
          try
            do_stuff_in_dir ("some/directory");
          catch
            warning ("An error occurred, but I don't care");
          end_try_catch
        endfunction 
        
        function do_stuff_in_dir (directory)
          unwind_protect
            wd = pwd ();
            cd (directory);
            do_stuff ();
          unwind_protect_cleanup
            # this will raise an error because I forgot the parenthesis
            cd wd
          end_unwind_protect
        endfunction
        
In this case, I will not get an error, right? I think it would be really
helpful if I got the error message from 'cd'. So, I think it might be
good if errors raised during interrupt handling could not get caught.
