I put it into a resign loop after 3 games. Left it resigning for a few hours, after selecting 'random' and speed to maximum, just to see what happens. 15 seconds for the first 1,000 resigns. After a couple of hundred thousand resigns, it had slowed to about 10% of the initial speed. It didn't crash. You could use an unlimited number of beads in the first move box, to stop people like me from finding the boundaries!
