I forgot to finish this off, you can have the kill action then run the stop
command and then everything is going from the same point.  Just executing a
system call to kill it means that the current request should finish cleanly,
along with everything else.

It may be overkill, but that's how I'd do it (just so any post-shutdown
scripts are always executed, etc)
