    I didn't look at the test-case yet, so I don't know what happens.

    But, before this comment, /sbin/init always ignored SIGSTOP.
    Now it is possible to stop init. Of course, user-space can't
    send SIGSTOP to init directly. But if you are ptracer, or send
    SIGSTOP to the sub-namespace, it should work.
