Right, of course I was thinking about 2.x
3.x has changed things.  It has also, by virtue of having the traceback part of the exception object,  declared the circular references thus constructed to be OK, which I'm not super happy about.  An exception object, if not explicitly cleared of its traceback, won't easily go away until the garbage collector collects it.  But that's a different story entirely.
