I suspect that there is some non-zero order-X (probably 2 or 3), where you just win more than you lose. Even for small programs.
Furthermore it would obviously help to enhance the clear_user_page() interface to handle multiple pages because that would nullify the startup/finish overhead of the copy loop.
