The for loops were just for example, it could easily be one function you want to track. The coderefs are needed because I'm basically trying to wrap a function call with args and track it over time (actually intervals. Not neccassarily the same thing.) The coderef provides a generic hook for performing an action. Now some functions might be builtins or return "0 but true" so the boolean is a generic way to let you defined the truth test. It is an optional argument.

I could see several uses. You could use it to track and monitor the performance of a different aspects of a server (HTTP Requests,IO latency, memory usage, etc). Mainly what it's for.
