Or you could just monkey-patch it so that 'hash' points to an old
hashing function. If the current hash() is kept in builtins as (say)
hash_320() or hash_272() or something, then anyone who wants the old
version of the hash can still get it.

Of course, it's still dodgy to depend on the stability of something
that isn't proclaimed stable, and would be far better to use some
other hashing algorithm (MD5 or SHA for uberreliability).
