I'm hoping to use the Job Hook system for DAGs. I would like to
utilize the "prepare job" and "job exit" hooks (to get
when the DAG is about to start, and once it's complete).
I don't want to knock too much on hooks, but unless you're using
them on non-Windows nodes I wouldn't recommend this approach.
The technology is still unstable on Windows. It's very easy to
crash a startd.
That pipe/signal bug never got fully flushed out did it?
