  Log:
  HAMMER 60B/many: Stabilization
  
  * Redo the estimated space usage calculation, it was horribly broken.
    There may still be issues with read+write memory maps.
  
  * Fix a bug in the reblocker that allowed it to exhaust all available
    space on the media.  While the reblocker eventually compacts the media
    it can actually require additional disk space while running.
  
  Note that file deletions in normal history retention mode do not recover
  any space unless followed by pruning, and may even require additional space.
  If worse comes to worse a full filesystem might have to be remounted in
  nohistory mode to recover space.
