Trivial fix:
Just wait a bit for the change the propagate.
(Waiting a fixed time is never ideal, but in this case it will dramatically lower the probability that the changes do not propagate in time)

> Looking at the point where it fails frequently, it looks like the problem is just that the ZK does not hit the (asynchronous) ZKWatcher in the PolicyObserver in time.
