I can reproduce the issue with Python 2.7. The problem is that
BZ2File.__init__() doesn't reset the object when __init__() is called twice.
For example, the following script fails with "too many open files" error,
before the previous file is not called:
---
import bz2
obj = bz2.BZ2File('bla.bz2')
for loop in range(1024*10):
obj.__init__('bla.bz2')
---
By the way, why do you call __init__() twice? Why not creating a new object?
BZ2File was rewritten in pure Python in Python 3.3. Python 3.3+ is not affected
by this issue.
