> 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.
