The handler that is being set in 'main' is never being removed--
i.e, there's no 'pop_eh'. Thus when exit_handler() is
called, it's generating a "Null PMC in say" exception
which then invokes the handler (which generates a
"Null PMC in say exception, which invokes the handler...).
You probably need a "pop_eh" right after 'handler:'.
