Unfortunately, my first message missed cc to 536546.DeleteThis@bugs.debian.org,
so could you please send your comment there also so it won't get lost?

I now wonder what was the idea of the original daemontools author --
does he suppose systems never get stopped or rebooted?
In fact I like the idea of daemontools, but if there's no clean way
to bring the supervisor down, the whole point of it is worthless.
