This doesn't really address the concern I have with regard to the con given 
above. The main reason is that the call profiler's monkeypatching is done 
potentially many times, and it performs an unpatch as well as a patch. This 
muckery can potentially really stuff over other components that also 
monkeypatch the same methods. Especially if they _also_ perform unpatching.

I'm not sure the consentual monkeypatch approach really solves this issue... 
and if the product has to be modified to make it register itself with the 
profiler, why not just have it include the (very simple) calls to the 
profiler instead?
