+1 On the "Is it really restartable?" comment. I spent a little time today
looking and trying to answer that question for all of our actors. I had to
quit when I got too scared! I'm pretty confident about the DAGScheduler
post-https://github.com/apache/spark/pull/186, but for the rest, not so much.
