Also even if another pool won twice in a row it wouldn't matter. Over the next few blocks ghash's blockchain would become longer and all bitcoin clients would accept it.
Oh well 0 confirmation has a lot of issues. But thanks for the info.
What I'm saying with the double-win is that it blatantly exposes GHash's ignoring of blocks they don't like, not that they would actually lose over time.
