    Didn't read through this much yet, but why do we need another in-kernel
    test that coul (AFAICT) be easily replicated in userspace? The same goes
    for several of the other tests, I think, actually. But at least with
    those, we have a history of keeping them around, so it's not too much
    burden [1].

    [1] Although there are some latent issues in these tests that are still
    getting get worked out (e.g., bad handling of 64-bit casting; too large
    of stacks; uninterruptibility). The latter two would not even exist if
    we were in user space.
