It's quite likely that I haven't done it right. Weak
reference support was only added recently and hasn't
been tested very well yet. I'll look into it.

Looking at object.h in the Python 2.3 distribution, it
seems that Py_TPFLAGS_DEFAULT already includes
Py_TPFLAGS_HAVE_WEAKREFS, which makes me think that
this list of requirements is not quite up to date.

Does anyone know more about what the requirements for
weakref support really are in 2.3 and later?
