Well, I was hoping to maybe have actual timing numbers from some better
hash, in case Matt can make one that is efficient enough. So I committed
the randomness improvement as a clear _improvement_ over what we had, but
it may not be the final version.
That said, I guess the same argument can be used for pushing it towards
stable too. Even if we end up doing something fancier, the patch is
clearly not any worse than what we have currently.
