    * The object auditor will now clean up any old, stale rsync temp
      files that it finds. These rsync temp files are left if the
      rsync process fails without completing a full transfer of an
      object. Since these files can be large, the temp files may end
      up filling a disk. The new auditor functionality will reap these
      rsync temp files if they are old. The new object-auditor config
      variable `rsync_tempfile_timeout` is the number of seconds old a
      tempfile must be before it is reaped. By default, this variable
      is set to "auto" or the rsync_timeout plus 900 seconds (falling
      back to a value of 1 day).
