I wasn't suggesting the PyStringObject be changed, only that the
PyUnicodeObject could maintain a reference. Consider:
s = fp.read()
u = unicode(s, 'utf-8')
u would now hold a reference to s, and s/s# would return a pointer
into s instead of re-building the UTF-8 form. I talked myself out of
this because it would be too easy to keep a lot more string objects
around than were actually needed.
