Ah, well, I suggest you write your own patch and implement it then, since you have no interest in any explanations at all having already made up your mind. You din't come here for help or information, you came to argue. right. that's it.

then the software is entirely correct in deciding to use any of those addresses in whatever order it wants. Complete and utter malarkey. But believe what you like. Might wanna READ the code before going on about the "additional burden"
