Sure looks like a resource leak somewhere (probably leaving a file open
until your program hits some wall of maximum simultaneously open files),
but I can't reproduce it here (MacOSX, tried both Python 2.3.5 and
2.4.1).  What version of Python are you using, and on what platform?
Maybe a simple Python upgrade might fix your problem...
