Here's a complaint. It's surprising that you can't use Event et al with isinstance. This is something I'm sure a lot of people run into (I did, many years ago) when they start to use these APIs. Once you do figure out why it doesn't work, it's not clear how to do what you want, since Event is private.

I have similar issues with bsddb. Here, there are Factory functions like "DBEnv" or "DB", creating "DBEnv" and "DB" class instances. Note the name aliasing.

I don't understand why these functions exist. It causes a few problems, like being unable to subclass the bsddb classes, for example.

For future bsddb4.6.4 (Late october, I think) I plan to remove the Factory functions, exporting the classes directly, and allowing subclassing. The code should be 100% compatible.

Any opinion?
