    What are the implications here when using an external journal?

    When the log is external the writes can still be reordered and create
    potential problems surely? (ie. write <fs-stuff> <journal thing>
    <fs-stuff> and since the <journal thing> is on a separate disk the
    ordering will be messed up)...
