So, iiuc, you're saying that the profiler sort of counts things multiple 
times--when you look at any individual part of the inner loop 
(wherever/whatever that might be), the entire time spent in that inner loop 
is "charged" to each individual part that you might look at?

So, you really can't tell which of those parts is the biggest contributor to 
the (presumed) problem?
