I tried the opening/closing world a bunch of times really quickly but all the computers (I had 15 side by side) turned on fine and ran the hello world program I gave them every time. I did notice something pretty important, when I had the frame machine move every .5 seconds, the turtles didnt reboot on average once every ten times, but when I set it to move every second it looks like it happens half that much and it seems to happen even less with 2 seconds, etc.
