Symbolics terminal emulator works lousy

	Some of the blame can be put on Symbolics.  When you reboot a Lispm, the
	processes that are running are not killed cleanly, so they can't close
	their connections.  SI:HALT doesn't kill processes because you might
	want to do a Continue from the FEP.  

    But that's exactly what would happen if you pressed the Halt button on
    any computer system.

And that's why Unix has /etc/shutdown, which tells all the processes to
kill themselves, waits for it to happen, and then halts the processor.

					     There is no command that I know of
	that does a clean shutdown.

    If you do a :Reset Network before you halt, that will definitely close
    everything on every network.

Reset Network is too big a hammer.  Not only does it close everything,
but then it starts reinitializing, which means that it opens a
connection to the namespace server.
