Pickling and unpickling extension types

single: __safe_for_unpickling__ (pickle protocol)
When the :class:`Pickler` encounters an object of a type it knows nothing about
--- such as an extension type --- it looks in two places for a hint of how to
pickle it. One alternative is for the object to implement a :meth:`__reduce__`

For the benefit of object persistence, the :mod:`pickle` module supports the
notion of a reference to an object outside the pickled data stream. Such
objects are referenced by a "persistent id", which is just an arbitrary string

By default, unpickling will import any class that it finds in the pickle data.
You can control exactly what gets unpickled and what gets called by customizing
your unpickler. Unfortunately, exactly how you do this is different depending
