    If the attacker gets full administrator-level access on your machine,
    there are a gazillion ways the attacker can prevent other admins from
    logging on. This patch can't prevent that. It sounds like this patch
    is trying to solve a fundamentally unsolveable problem.

    A useful slogan: "Don't forbid what you cannot prevent."
