    hammer2 - Stabilization
    
    * Do not scrap deleted + modified chains unconditionally, this will mess
      up operations on unlinked-but-open files.  Also fixes an assertion which
      was getting hit and fixes poudriere test run stdout EBADF errors on
      unlinked fifos.
    
    * Optimize handling of the DESTROYED flag to restore the feature where a
      rm -rf can get away with doing almost no write I/O.
    
    * Remove a bunch of debug stuff
