That approach (or a similar one) could actually be integrated into
StringIO and BytesIO. As long as you only write() at the end of the
in-memory object, there's no need to actually concatenate.

And it would be much easier (and less impacting on C extension code) to
implement that approach in the StringIO and BytesIO objects, than in the
bytes and str types as Larry did.
