It is my understanding that the reason why this is is high performance situations. You have some other system that can figure out if something fail, but with this feature you can move the high water mark so that you don't have to redo as much. But if you got the timing right and there is a failure you can go ahead and assume that when you restart again you'll be getting some stuff that you already processed. The problem is when you don't have this for mailing before the auto commit. It is meant to be done far after processing in my reading of it, but it does certainly seem like there's a contradiction that it should auto commit but only stuff so many milliseconds before the auto commit time?
