      Description

      The list used to track all PerRegionTable-s does not need to be maintained as a double linkedlist. Entries deleted from the _fine_grain_regions table are reused in place (for the all-regions-list), and thus unlink_from_all is not used any more. Therefore the all-regions-list can be maintained consistently even a single linkedlist.
