Right.  It provides both methods, and they implement the standard
protocol; e.g. getstate does not return _v_ attributes.

It provides the implementation.

Regardless, it means that if you have a chain of inheritance that goes
derived class -> Persistent -> base class, then you're base class's
__setstate__() isn't going to be called.
