But why not simply:
MyClass -> MyMixin -> io.FileIO -> IOBase
?
Is there something I'm missing that prevents you from doing this?

I understand, but that's at the price of an otherwise useless
indirection layer, which will also make _pyio even slower that it
already is :-)
(I admit, however, that _pyio shouldn't be used in normal circumstances,
so this is not a showstopper argument)
