Oh.  That's kind of sad, but I can live with it, I guess---I
hardly ever actually do that.

I still don't get what goes wrong if we leave the unwinding
undone until the debugger is exited or an exception is
handled.  It would require a little machinery, I guess, to
run unwindings for a handled exception in the proper
context...
