There are cases where a rebalance improves dispersion, but doesn't improve balance. This is because the balance of a ring builder is taken to be the balance of its least-balanced device, so if there's a device that has no partitions, wants some, but can't get them, then we'll never save the ring builder even if every other device in the ring got better. We can detect this situation by looking at the dispersion number; if it changes, then the rebalance needs to be saved in order to continue to make progress.
