Hi Evan,

Couldn't you do this by overriding _q_traverse on your root
Directory instance?  Something like:

    def _q_traverse(self, path):
        # code A
        try:
            result = Directory._q_traverse(self, path)
        except TraversalError:
            # code B
            raise
        # code C
        return result

HTH,

  Neil
