If I got Tinker's point right, it's what I was thinking about listening Lujo's speechmaking about 'broken' PISORF - it's just another strat, approach, from bunch of other stuff, and yeah well okay, you found it, showing how to abusing it, okay, you are smart and so on.
But why it's 'broken' and another stuff is not? It's just one of the edges. I guess it supposed to be that way. By devs. So there is nothing to be fixed.
