subprocess leaks memory on win 7 64bit (Python 2.7.3 32bit).
The following code snippet will fill up memory slowly but completely after running it multiple times. When python exits the memory is not freed.

>>>>>>>>>>

import subprocess
import shlex

for i in range(0, 10000):
    p = subprocess.Popen(shlex.split("ipconfig", posix=False))

    result = p.communicate()

print "end"

<<<<<<<<<<

I don't see any leak on Linux with Python 2.7 or Python 3.3. How much KB does subprocess leak per process?

20kb exactly, I can confirm it is only on Windows. I'm currently running some tests to make sure it isn't a general Windows problem. I'll post an update as soon as done.

Oh, that's a lot. Can you please also try with Python 3.2?

Yes, ok, my sincere apologies, I should've tested more thoroughly before filing a report here. It seems to be a Windows problem. I could replicate the issue using a batch script (and Python 3.2 for that matter). I'm still in the dark about what it causes, but here's a more detailed problem description for those interested.
