    Ok, I have looked at the draft now, and I don't think I was overly
    pessimistic.

    If I read it right, all the memory ordering operations are defined for
    _single_ objects. So if you want to do the kernel kind of memory ordering
    where you specify ordering requirements independently of the actual
    accesses (perhaps because the accesses are in some helper function that
    doesn't care, but then you want to "finalize" the thing by stating a
    sequence point), it seems to be impossible with current drafts.

    Oh, well. Nothing lost. I didn't expect the thing to work.

    Linus
