> If there are too many regions in one overlapped group (by default, more than 10), hbck
currently doesn't merge them since it takes time.
> In this case, we can sideline some regions in the group and break the overlapping to
fix the inconsistency.  Later on, sidelined regions can be bulk loaded manually.
