    Thinking more about it, I suspect it is (once again) wrong to let the
    thing that does the execve() control that bit.

    Generally, the less we allow people to affect the lifetime and
    environment of a suid executable, the better off we are.

    But maybe we could limit /proc/*/exe to at least not honor suid'ness
    of the target? Or does chrome/runc depend on that too?
