There is no general solution: http://en.wikipedia.org/wiki/Halting_problem
But you can stop your app from hanging by running scripts on another thread. You can also stop the thread after a certain amount of time, thus accomplishing a similar thing as a cycle count. However, again, there is no general solution.
