--- Comment #1 from Steven Schveighoffer <schveiguy at yahoo.com> ---
There are 2 options other than adding just a limit. First, we could use
tortoise and hare algorithm to detect the cycle. Second, we could mark each
exception somehow as it is printed, and then unmark them after the printing
algorithm is over.
