+ alias exit 'echo "Use ^D to exit"'
+ alias logout 'echo "Use ^D to logout"'

+ They are there only as a joke, but they got me thinking.  Suppose I
+ also say "set ignoreeof".  How do I logout?  No fair using unset or
+ unalias or alias -- they give any number of obvious two-liners.  Can
+ I do it with a one-liner? (Using ";" is cheating too :-).
+ 
+ My first impulse was "\exit" or "\logout".  No dice, since a leading
+ \ to undo aliases also undoes builtins.  This soon led me to exec;
+ the first quiet one I tried was "exec true"; it worked.

kill -KILL $$

However, this can leave stopped jobs lying around.  Now, what if both
"kill" and "exec" have been aliased to something useless?
