> {\{MobFileCleanupUtil}} iterates over real data regions but creates
> {\{HRegionFileSystem}} using the MOB pseudo-region. \{{StoreFileTracker}} therefore
> reads the wrong directory and returns no store files.
> Old store files without \{{MOB_FILE_REFS}} are missed, so cleanup may archive MOB
> files that are still referenced.
> Use the \{{RegionInfo}} from the current region directory when creating
> {\{HRegionFileSystem}}.
