Just asking the dumb question here, but is this intended to return an int? sys.maxsize does not appear to be the max positive 32-bit int.

Should it use sys.maxint instead?

CC @davies the real question is whether this hash is intended to be 32-bit or 64-bit, and my Python knowledge is too limited to reason about this. It appears that it's computing a 64-bit hash given the size of sys.maxsize but maybe that's platform dependent or something. Anyway: I kind of suspect you're right that it's 32-bit, but I think that has to be verified first.

The h become a long when h *= 1000003, even after h &= sys.maxsize or (maxint).
The fix looks good to me.
