Code review comment for lp:~allenap/maas/dev-services-shutdown

As I said this morning, it looks like the services (celery, apache2, postgres) take a few seconds to actually stop and you get in trouble if you try to start them up right after they've been told to shutdown by svok. If one waits a couple of seconds after hitting CTRL-C, then the services can be re-started ok.

This is not ideal but already a massive improvement over what we have now.

This is probably worth backporting to 1.2 btw.
