[Numpy-discussion] Python memory management issues using Linux. Maybe Numpy related.

I have had issues with Linux (Ubuntu 10.04 x86_64) not releasing memory
back to the OS. I have code here the exhibits the issue:
http://stackoverflow.com/questions/5975255/memory-allocated-to-python-in-the-os-is-never-released-back-in-linux-even-after-g
Then I read at http://pushingtheweb.com/2010/06/python-and-tcmalloc/
that this was a problem fixed by compiling your own version of Python
using the TCMalloc library which I have now done. The issue is still
exhibited so I was keen to know if possibly it was because numpy is
compiled and linked to the default memory management library (not sure
if this is true or how this works but would I also need to compile numpy
linked to the TCMalloc library). Let me know if anyone has any insight
on this issue. Or if it isn't related to numpy at all.
