    The RT thing isn't particularly about scaling per-se, its mostly about
    working at all.

    This thing still relies on disabling IRQs in the slow path, which means
    its still going to be a lot of work to make it work on -rt.

    It also heavily relies on bit-spinlocks, which again is going to need
    changes for -rt.

    But yes, the lockless fast path is nice, I'll try and get around to
    reading it.
