Yes, but the dict is still keyed on the traceback alone, and only the
first header for a particular traceback is stored.  If two different
exceptions occur at the same line of code and sharing the same
traceback, the second exception would be counted as a second
occurrence of the first, effectively squashing any reporting of the
second exception.
