What does "memory efficiency" mean to you? Are you asking
how to eliminate memory leaks?

While I have a great deal of interest in memory management,
my general reaction to your question as you've posed it is,
"Don't; concentrate for now on good Python style."

I agree but for monitoring...

I've had good luck with executing a popen to grab and parse output
from ps -Af and pass it your own process ID as the search. It adds
overhead to the cpu exec time but it is much less than 1sec so you
won't see it.

Fair enough.

Did you intend to suggest "ps -F"? While ps remains not-so-well
standardized, I know of no version where "ps -Af" details *memory*
usage.

Parsing can be simplified with such invocations as
ps -o pid -o rss -o size -o cmd
(which can itself be rewritten in various ways, depending on the
flavor of ps involved).
