Also, DW was running 'sudo shutdown -p now' which is indeed immediate .. 
'shutdown -p +1' (say) sets the shutdown countdown to one minute, makes
(w)all sorts of noise then and again at (as I recall) 30 seconds to
zero, plenty of time to logout from other things and (auto)run any other
scripts you like before the shutdown-initiated rc.shutdown stuff. 

Furthermore, if you change your mind you've got time to kill shutdown
itself before the timeout.  'sudo killall shutdown' should do the trick.

Cheers, Ian
