    Yes I heard about that, but since it's not a single bit setting
    there are lots of different ways it could be broken in theory.

    To check it you really need to have a tool that knows about
    all the registers and checks them all.

    It's a bit like checking if someone speaks a foreign language
    by asking them a single question with a one letter answer.

    Yep.

    It's asking a question with a one word answer where you don't
    know the correct answer.
