    Oh, well.. Journalling sucks.

    I was actually _really_ hoping that somebody would come along and tell
    everybody that this whole journal-logging is stupid, and that it's just
    better to not ever re-write blocks on disk, but instead write to new
    blocks with version numbers (and not re-use old blocks until new versions
    are stable on disk).

    There was even somebody who did something like that for a PhD thesis, I
    forget the details (and it apparently died when the thesis was presumably
    accepted ;).
