  22. The best thing to do for text windows would be what VDM's do for
  23. graphics sessions.  Create a virtual display space for each windowed
  24. session (just like full-screen sessions get) and update the window
  25. based on a timer.  So your window will update every 10th of a second
  26. or so.  The refresh speed can be s system setting just like it is a
  27. DOS setting.
