I'm not convinced that this is better.  But as an experiment, I decided 
to see if I could make emacs do what you want by having a system 
shutdown trigger 'save-buffers-kill-emacs' instead of 'kill-emacs'. 
What happened was that Windows complained that emacs was preventing it 
from shutting down, and it gave me the choice of shutting down anyway or 
canceling the shutdown.  I chose the latter, at which point I was faced 
with a non-responsive emacs that had to be killed.

I don't have any further ideas.
