If you find out how to stop this, let me know.  Most of the programs I
write can't be stopped by the ctrl . command.  Usually, though, I just
kill mathematica from the ctrl-alt-delete screen.  I rarely have to
reboot the machine, but it does happen occasionally.  I wish the 256
limit on recursion applied to error messages.
