Do You register Your function using atexit() ?

This works perfectly fine and as expected for me. I would wonder if the
interpreter was shut down and tries to execute a cleanup thereafter.

Checkout following example code. You may also have a look at the
/lib/atexit.py module see how it works.

import atexit
import sys
def foo():    
    print sys
    
atexit.register(foo)
