    Ordering.orderList generates a "set operation not supported" exception when
    executed on a query with a specific pageSize.

    I understand how this bug could come about, and I'm guessing that I need to
    manually forcing each fault to resolve before calling orderList.

    However, I suspect this should be handled by the framework rather than the
    user.
