    :> How does it get 255+ references?

    :I don't know exactly at this point. I can reproduce the situation at will
    :with (in kernel) test code, but I don't know what exactly causes it in the

        If you just put a KASSERT() in for the 'reached 255' case the backtrace
        will have a good chance of containing the likely culprit.
