    b, Fix possible data corruption issue caused by data sent by bad peers during endgame
       (this one I am not completely sure of, but when looking at the relevant bug record:
    [5] http://trac.transmissionbt.com/ticket/1242
        there is written:
    [6] http://trac.transmissionbt.com/ticket/1242#comment:1
        "My theory is that for some reason Transmission will download a corrupt part
         from someone but not realize it until you do a manual verify. At this point
         T will recognize the bad part and redownload it from the same person, which
        just causes the problem again."

        so to prevent someone from successfully downloading content of some torrent file,
        for an attacker to should be enough to download a part of it, corrupt it and
        share it. Not sure about the algorithm, Transmission decides which torrent
        to retrieve content from, but if it is deterministic / predictable behavior /
        algorithm, such attack could succeed).
