Okay, i'm looking at this and i believe the problem is that the profiler does
far too much work on entry/exit.  Requesting the name of a Function is a
generic property lookup, and hence is a far too heavy cost for function entry
and exit.  I think a better approach would be just to store the function
pointer, and retrieve the actual information once profiling is complete.
