    The when part is what looks to make it racy. I'm guessing that we're
    relying on udev to create those loop nodes. If so, I think any scheme
    that creates more on demand would give transient mount errors while
    it's waiting on udev to create more nodes.

    Perhaps if we were to start with 8 loop nodes at init (as we have in
    2.6.21), and then always maintain a margin of 8 (or 4, or...) when
    they start being used or detached?
