Call BZ2File_iternext() on closed file doesn't release the lock. Example: ----------- import bz2 obj = bz2.BZ2File('/etc/issue') obj.close() try: # acquire the lock obj.next() except ValueError, err: # but don't release the lock print err # DEAD LOCK here obj.readlines() ----------- Attached patch fixes this bug.
