      This is exactly what Self does (except for the gray box and red lines)
      - Randy and I put this code into 4.0, in '95 (before Squeak).  See our
      CACM paper (vol 4, #4).  When it was built, the UI was pretty robust
      -- we had numerous sessions with multiple users in the world at the
      same time, doing development.  Randy and I demo'd this at ECOOP 95.
      If it's fragile now, it's because bitrot has set in somewhere, not
      because there is an inherent problem.
       


      How can I get this paper?

      The VM has no idea how much real memory is installed.  That certainly
      isn't the problem.
