> In a worst case situation, it may be helpful to have an offline .META. rebuilder that just looks at the file system's .regioninfos and rebuilds meta from scratch.  Users could move bad regions out until there is a clean rebuild.  
> It would likely fill in region split holes.  Follow on work could given options to merge or select regions that overlap, or do online rebuilds.
