Ah, this was the one mentioned in the open-space talk. This looks
very similar to a much earlier version of zdaemon. A disadvantage I
see with it is that it requires modifying a Python application to use
it. We moved away from that model with zdaemon, which can wrap any
application. We use it to make the spread daemon sane for example.
Does ll.daemon provide a monitoring process that restarts an
application process if it exits abnormally?

Yes, I've heard similar things.
