As various people pointed out to me:
http://wingolog.org/archives/2007/11/27/reducing-the-footprint-of-python-ap...

That might help.

Aside from that (rant), I seriously dislike Python's memory management and
even more the fairly arcane ways people have to go about
debugging/troubleshooting some 600 MB to 2-3 GB(!) of resident memory use by
Python.

Personally I consider this the weakest point of Python. Given the fact there
is a garbage collector this sort of keeping track of memory seems a bit
contradictory to the concept of garbage collection.

(And yes, I am investigating this and also how to get it leaner and better.)
