Yes, this may well be correct. My only TRUE wish for tuning performance of Python applications is to have SOME ways to measure memory footprints with sensible guesses about where they come from -- THAT is where I might gain hugely (by fighting excessive working sets through selective flushing of caches, freelists, etc).

Any idea how to actually do this?
