Thinking about this a bit more, if an instruction gets emulated 10
times then I don't care, since it's probably only cost me 10
microseconds or so.  If it gets emulated a million times then I might
want to look at it.  So in fact this approach doesn't give me the
information I need to know whether there is a real problem or not.
