Summary: Leak in tarfile.py
Initial Comment:
There is a leak when using the tarfile module and the
extractfile method. Here is a simple example:
$ echo "grrr" > x.txt
$ tar cf x.tar x.txt
$ python
Python 2.4.2 (#2, Sep 30 2005, 21:19:01)
[GCC 4.0.2 20050808 (prerelease) (Ubuntu
4.0.1-4ubuntu8)] on linux2

>>> import gc
>>> import tarfile
>>> tar = tarfile.open('x.tar', 'r')
>>> f = tar.extractfile('x.txt')
>>> f.read()
'grrr\n'
>>> del f
>>> gc.set_debug(gc.DEBUG_LEAK)
>>> print gc.collect()
gc: collectable <ExFileObject 0xb73d4acc>
