I was twiddling with some of the internal array parameters. I may have
set an array size too small. This might be causing your crash.

I think it is amazing (and terrific ) that two instances running show only
about a 10% slowdown per process over 1 instance running. I expected
a lot worse.

Note that the 2Ghz Athlon showed about a 30% improvement over my
laptop. This is in good agreement with their relative clock rates.
