I can always C-g and execute this command but I would like to do it
automagically in my lisp programs so, unfortunately, this isn't exactly
an option.  Half the time, I forget the freezes are due to Tramp
inability to speak with the remote machine too...

If I let-bind tramp-connection-timeout to 1 in the above example, Tramp
still tries to talk with the remote machine.  :-( Am I misunderstanding
your suggestion?  Should I be using with-(tramp-)timeout?
