-Speed up attribute access on instances of :mod:`io` classes and their
-subclasses by storing instance attributes and weak references in the object pre-header. The ``__dictoffset__`` and
-``__weakrefoffset__`` attributes of these classes now report the managed offsets, and C extension types that subclass an :mod:`io` class can no longer declare their own ``__dictoffset__`` or ``__weaklistoffset__`` member.
