Hashes are used to determine inequality, not equality. If two objects have different hashes, they are not equal. If two objects have the same hashes then other, more compute intensive tests can be run to determine equality.

If two objects are equal (as determined by the isEqual: method), they must have the same hash value.
My question is whether the reverse must also hold?
