      Various optimization for better DoM performance. So far they are:

      • glimpse ahead. Issue glimpse from MDT in advance and return size on client along with other attributes.
      • read-on-open. Read file data at OPEN and return to the client
      • lock bits convert instead of cancel. It is separate ticket because it is useful for all files, not just DoM.
