This post on The Daily WTF reminds me of the startup script we had for Basternae 2 in the early days:

Since the codebase would tend to hang or crash, we would have to watch for the process and restart it if it was missing. If the CPU usage was above a certain amount for more than about a minute it also told us that the code was in and endless loop, so the process would have to be killed and restarted. It wasn’t not quite as intricate as the WTF setup, but it was still pretty kludged.
