fat lot of good that does a script

What about most users that didn't write the "badly written daemon". Are
they suppose to learn how to maintain other people's stuff???

Again, this oversimplifies the problem. We can make ssh difficult to use
or easy to use -- gee why do you think Windoze is so popular --

since ~ will unconditionally close a terminal window, what's wrong with a
config option to do this automagically if the sysadmin wishes to configure
sshd in this fashion. Give me a good reason (other than academic) why when
the user or script says "bye now" that sshd should not take them
seriously.
