Pardon my ignorance but why does Python do reference counting for truly global and static objects like None, True, False, small and cached integers, sys and other builtins? If I understand it correctly these objects are never garbaged collected (at least they shouldn't) until the interpreter exits. Wouldn't it decrease the overhead and increase speed when PyINCREF and PyDECREF are NOOPs for static and immutable objects?
The check what kind of object you have takes time, too. Right now, just counting up or down is most likely faster than that check on every refcount operation.
