    Description

      On split, usually the two daughter regions end up on assignment list at same time. Dependent on cluster state and what balancer says, when a server checks in, we'll assign at least two regions in the one go so daughters then end up on same server. This patch makes it so we don't assign contiguous regions in the one assignment.
