I have tried it on a titanium notebook using osX 10.3, and I have the 
same results (crash).

I'm a little like the snail crawling over a razor blade-- bleeding edge 
while not realizing where I'm going!

If anyone is interested in trying this out for themselves,  I have 
placed a copy of the offending code at
http://geohive.nr.usu.edu/~sanduku/swarm/tyler-17-10-03.tar.gz

If you enter the string 't50' in the initialInfestation value in the 
DataFileSwarm window, you should find  the offending behavior happening 
after 26 time steps.

The file is largish (5.3M)-- sorry about the size.
