Brent, There is no confusion.
Sure, that's just the standard kiddy book diagram of a black hole with which everyone agrees (except Jesse Mazur who thinks nothing actually enters a black hole but instead piles up on the event horizon boundary - see his posts). But that doesn't address the point of my question. What "is in there and has to come out" is the gravitational effect of the mass that falls in which was the point of my question and my answer.
