"Also, this is only for plain (byte) strings, not for Unicode strings;
as of Python 2.4.2, Unicode string concatenation remains
un-optimized."

Has the same optimization been implemented for Unicode? The page
doesn't mention Python 3 at all, and I would guess that the realloc
optimization would work fine for both types of string.
