 discussed earlier, if the reference count drops to zero, we might
 cause code to run that calls back into the object.  In addition,
 because we now support garbage collection, we also have to worry about
 code being run that triggers garbage collection.  If garbage
 collection is run, our \member{tp_traverse} handler could get called.
