------------------------------------------------

I can see that in case of splits you add some new qualifiers indicating that
the new daughers have replicas and the same is marked with a new column in the
META.
The first comment here and the first patch for branch-1.2 has some logic in
CatalogJanitor to trace out this new column and use that as an indicator to
show that there are still references to the parent replica. And once the
daughter replicas are opened those new columns are deleted.
But in the merged patch and the master code that I am checking there is no such
logic in CatalogJanitor. So how is that part handled where we keep the parent
region from being deleted?
