This reports the completion status of the most recent create or delete operation performed against the user-group or membership tables. Admins poll this after writing to one of the delete-action objects, or creating an entry, to confirm the operation actually succeeded, since a failed create or delete wouldn't otherwise be visible. For example, a value of createTableFull(2) after attempting to add a user group tells the admin the group table has hit its capacity and the group wasn't created.
