The main reason why vos release is sometimes slow is because it has to
break all the callbacks held on the read-only replicas.  If you're
releasing a heavily used volume, this can take quite a while.

Finding a way to make breaking callbacks go faster would be useful in
several areas, not just this one.  (It would make it faster to restart a
file server, for instance.)
