This is the winning answer.  Tested and accurate on all points.  I will
give your DIMM to CLUE at the next meeting, per your instruction.

Sorry, I won't be there.  If my answers are the winners, consider
donating it to the CLUE projector fund cause.

There are several ways.  1. Find the system that originated the
connections. Lot out from the inactive terminals.  2. Find the PID of
the shell on your system that is running on the inactive tty.  (use ps
-axuw and grep for the tty name)  Kill that PID.  3. Use a program like
'force' that lets you send characters to another tty (as root).  Send a
^D (EOF) to that tty - then the shell will exit, the connection will
close, and the handler daemon will die.

Yes.  You could test this by doing a loop-iso9660 mount of the image.
