----------------------------------
[~huaxiangsun] Maybe you forget add the Procedures Last round generate into
ongoingMergeProcedures, you cannot sure it finish in last round.
I can work, but when GCMultipleMergedRegionsProcedure finish or failed exit,
you must clean the Procedure in ongoingMergeProcedures
> CatalogJanitor resubmits GCMultipleMergedRegionsProcedure for the same region

> If a lot of regions were merged (due to change of region sizes, for example),
> there can be a long backlog of procedures to clean up the merged regions. If
> going through this backlog is slower than the CatalogJanitor's scan interval,
> it will end resubmitting GCMultipleMergedRegionsProcedure for the same
> regions over and over again.
