    This is not necessarily true for read requests.

    If each read request is synchronous and the process will
    generate the next read request after the current one
    has finished, then it's quite possible to clog up the
    queue with read requests which are generated at exactly
    the same rate as they're processed.

    Couldn't this still cause starvation, even with your patch?

    regards,
