It seems to happen outside as well? I've run it just as a standalone
program. It's seems like maybe it's something with memory.. but I have a lot
(2gb RAM, 1.8 Ghz on Windows XP -though will ultimately port this to LINUX).
Anyway, it runs, but then becomes very slow... ultimately crashing sometime
during the second of the two print figure loops.
