Yes we can all deal with it but as a practice to my mind it shows
sloppy planning on the part of the designers.  CANCEL and FORCE should
be used in error conditions, not as a part of normal operations.  This
sort of thing can bite.  If I understand other postings and from what
I recall from 20 years ago when I was an active systems programmer,
FORCE ARM was a last resort, not a normal way to do things.  If we
believe in such things as orderly shutdown, then everything should be
designed to be shut down.

Of course, I may be spoiled.  When I shut down my Windows XP and
Windows 7 computers all of wild and wonderful processes (anti-virus,
printer monitor, etc.) automagically shut down when either shutdown or
restart is selected.
