Does anyone know the best way of having CentOS parse the current process list for a specific process name and determine if the CPU usage has been above a specific threshold for X amount of time? If it does, kill it and re-execute the process?

Thoughts would be appreciated.

I seem to recall an /etc/limits or limit.conf that does that as part of the OS. You can set various thresholds and it'll kill processes if they exceed them.

I had to do that to prevent my friend from hacking in and fork bombing to crash my server. You'd be surprised how much better your security gets when you've got someone telling you how they exploited it.
