I believe that's the purpose of the PySizer project (one of the "Google
Summer of Code" projects), which was recently announced on this group
(I'm sure any search engine will be able to direct you to it, anyway).

I have not checked it out, because my purpose is different -- mine is
not a Python-related leak at all, just a leak within C code (which
happens coincidentally to be a Python extension module).
