Feel free to make that text more accurate, sure. As long as we agree that the problem exists, I see no need to argue. The relevant code is complex enough for me to welcome any insights from anyone, certainly from you. I don't claim to have a 100% clear vision of everything that's going on with these flags. I write that text so that we don't forget the problem, and so that maybe someone will want to work on this, and make the maintenance easier.
