Ah, thank you for the clarification!

Also, I really appreciate your testing with the rest of the series as
well. It will be good to have any potential problems identified early
(I'm trying to get v9 ready as soon as I can here, as its fixed a
number of smaller issues - However, I've also managed to uncover some
new problems in stress testing, so we'll see how quickly I can chase
those down).
