Please identify the Python version and OS+compiler+C 
library in use.  The process size remains steady for me under 
current CVS Python on Win2K w/ MSVC6.

A true leak is possible but unlikely.  More likely is that your 
platform C malloc()/free() decide not to return memory to the 
OS.  If so, that's outside of Python's control
