Sure! I can release what I have at the time. The risky part
is that these are *many* changes, with the danger of introducing
subtle bugs, so a review of the changes would be definitely
helpful.

Conceptually, it is a different thing, because sizeof(void*) and
sizeof(size_t) may differ on some platform. For practical purposes,
they propably won't differ on any platform supported by Python.
