[Vm-dev] Intermittent failures on InterpreterVM build

[Frank Shearar]

http://build.squeak.org/job/InterpreterVM/200/console shows a
successful build of r2688
http://build.squeak.org/job/InterpreterVM/201/console shows a failed
build of r2688

The failure was because the watchdog timer killed the build. I don't
know the ins and outs of either the script driving it (I've glanced at
it, but haven't taken the time to understand it) nor of VMMaker, but
when I've had builds hang it's normally for the extremely unhelpful
reason of a dialog popping up on a screen noone will see, either
notifying of an error or asking the user a question.
