A simple way to do this is to use a file on disk to trigger 'stop this
service'. So shutdown would be:
 - write a stop file
 - wait for the process to finish

That said, there is a bug open for cronscripts to have a single
unified 'do not run' check - and the buildd sequencer would be better
off leveraging whatever check it uses, so you don't need a special
mechanism. https://bugs.edge.launchpad.net/launchpad-foundations/+bug/607391
is the umbrella bug about it - please do jump in and itemise what the
buildd managers constraints on that check would be.
