Sorry, I've been lurking & not contributing... Is it possible to have  
the daemon log what it's doing as it's shutting down, and how much it  
has left to go. That way the init script could monitor that to make  
sure that the daemon is actually shutting down and not simply hungup  
somewhere...

Then the init script can simply SIGKILL if the daemon isn't actually  
doing anything, and (Possibly) run it again to simply flush the journal.
