              -- entry and sets this object to valid(1) or aborts,

              -- determines that an entry has been in the
              -- underCreation(3) state for an abnormally long time,
              -- it may decide that the management station has
              -- crashed.  If the agent makes this decision,
              -- it may set this object to invalid(4) to reclaim the
              -- entry.  A prudent agent will understand that the

              -- and will allow for that possibility in its
              -- determination of this abnormally long period.
