That's an interesting thread. It certainly gives me a new understanding of the
issues.

Since I need a solution _now_ I'm going to go with Daryl's daemontools patch
but will rename his `postrun' script to `finish' for compatibility reasons.

When the new pipe-tools comes out I'll likely evaluate that, too.

On the topic of `finish' script compatibility: if the three approaches cannot
agree on a standard calling convention it would be useful for a finish script
to be able to detect under which supervision tool it is being run. That eases
migration between the various solutions.

Thanks for your responses so far everybody.
