Hrm.  So replace the last sentence with something like:

   The fix is to use the index into the array, instead of
   a pointer to the beginning of the array, so that the count
   for each element in the array in incremented by the
   corresponding callback.

That feels a little clunky but is it closer to what you were
thinking?

Thanks for the review!
