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.
