This is good timing, because I have increasingly been thinking about how
to serve multiple users with graphical displays from SIMH.  Possible
uses are:

 - Knight TV displays... we have solved this in an ad-hoc way.
 - III displays driven by the WAITS operating system.
 - "NG" and raster displays for the SITS PDP-11 timesharingsystem.

Opening multiple windows on the host display doesn't help much when
there may be users coming in from the network.
