    Yeah, I was thinking instead of, and hoping that would be enough.

    What exactly do you mean by failed affine wakeups? Failed because
    wake_wide() said we don't want one, or because wake_affine() said we
    can't have one? If the later, my thought bubble may have just burst,
    but it still "feels" right.
