IIRC this was because UserDict tries to be a MutableMapping but abcs require new style classes. Are there any use cases for UserList and UserDict in new code, now that list and dict can be subclassed? Inheriting from list or dict isn't very useful as you to have to override every method to control behaviour.

Benjamin fixed the UserDict and ABC problem earlier today in r82155. It is now the same as it was in Py2.6. Nothing to see here. Move along.
