Because all of the overhead of the inspector happens on call entry and return
the profiler will greatly exaggerate the runtime cost of call heavy code.

To be able to store just the function object pointer you'll need to be add
logic so that we can gc any objects that the profile references (i imagine once
profileEnd() occurs you can immediately actually extract all the profile info,
and drop the funciton object references, but you'll probably want to wait until
there are no active profiles)
