Uh, yes, indeed. I guess that my explanations don't survive an
interpreter shutdown, after which the reference counter of the object
effectively drops to zero. I don't see how this doesn't crash Python
when you exit. It could be that the gc is not called after the
reference from the import mechanism was effectively removed -- type
objects after a PyType_Ready() are full of ref cycles. But it's all
quite obscure.
