__del__ and wisdom

Every time discussion about __del__ had come up I had thought to myself, "yeah, but I'm being careful to not have reference loops -- /my/ classes are okay." and then... BITE! But hey, it wasn't a reference loop that got me, it was data being written back to disk after the disk portion had c

ANN: dbf version 0.92.002 released
