The impression I got from the bug report was that a command 
`ns-power-off' was being bound to a key in Emacs. But it sounds 
dangerous to make such an event a lisp level event and allow arbitrary 
user code to delay or prevent shutdown of the system. On Windows, the 
equivalent event auto-saves all buffers and exits, in a way that is not 
held up by an infinite lisp loop in user code.
