This question interests me intensely--which is why I'm taking
so long to answer it.  I'd love to write a book on resource-
management techniques.

However, you need an answer now, and it probably won't serve
you even to wait for the well-crafted response I had in mind.
Let me put your progress in your own hands:  if you want "a
way to dump the process's object hierarchy", it's probably a
good time for you to read <URL:
http://python.org/doc/current/lib/module-inspect.html >.  Does
that give you what you need, for now?
