The preceding paragraph by Didier saved me a lot of embarrassment later
on. Just because you can run the pipeline at a command prompt doesn't
mean a process supervisor will handle it right, and an afternoon of
experimenting with Runit confirmed exactly what you say in your
preceding paragraph.

So I found a slightly different way to code the Python program such
that when you kill the Python program, you kill inotifywait, and when
you kill inotifywait, you terminate the Python program, and confirmed
that my new way works well in Runit, which probably also means it runs
well in daemontools-encore or s6, and very well might run right, out of
the box, when declared as a respawn in /etc/inittab or as a command
in /etc/rc.local. I predict I'll have something working by tomorrow
night.

Thanks,
