how to get memory info from python?

[Gardner Pomper]

Hi,

I'm pretty new to python, but I have not found any way to find out how much
memory is being used by my python application. I have some fairly large data
to load in and I am concerned about hitting the 2GB limit on my 32 bit
processes.

I would like to have the program check itself for memory usage. I know I can
get the memory information from a 'ps -l'. Btw, I will be running on AIX and
linux, although I may do some development on Windows.
