  I tried this, and voila, it worked. The default applications went
away, too:-), but I managed to restore them.  It was puzzling when I
had 8 ComancheServers in my image:-) I now understand that the
'entryPoints' inst var (transitively) holds the continuations that
hold those contexts.

  Thank you for your suggestion!
