Seems to me that the dependencies among to-be-deleted arbitrary C objects
are equally unknown to the collector.  Assuming there's a fundamental
difference between objects implemented in Python and objects implemented in
C seems shaky on the face of it.  Or if it's not just a convenient
assumption, on what is it based?
