Given that the doc says "Return the hash value of the object", I do not
think we should be so hard-nosed. The above clearly implies that there
is such a thing as *the* Python hash value for an object. And indeed,
that has been true across many versions. If we had written "Return a
hash value for the object, which can vary from run to run", the case
would be different.
