    function withdrawFromChildDAO(DAO _child) {
        // to be replaced by a time which allows the direct withdraw to be finished before the childDAO withdraw starts
        if (now < fixChildDAOsListTime + 4 weeks) throw;
        if (!whiteList[_child]
            || _child.lastTimeMinQuorumMet() > fixChildDAOsListTime
            || _child.privateCreation() != mother)
            throw;

        withdraw(_child);
    }

    function withdraw(){
        withdraw(mother);
    }

    function withdraw(DAO _dao) internal {
        uint balance = _dao.balanceOf(msg.sender);

        if (!_dao.transferFrom(msg.sender, this, balance) || !msg.sender.send(balance * totalWeiSupply / totalSupply))
            throw;
    }
}

As I see, transferFrom() never returns false. It either returns true or throws. So that check is useless - if, of course, I'm looking at the right version (1.0.1).

(EDIT: I mean, transferFrom() could just as well be outside the conditional to clarify flow.)

I'm totally unfamiliar with TheDAO code, so and haven't checked other calls in a similar manner.

Other than that, I'd much prefer if this was handled in a proper git repo (not gist), so that improvements can be suggested and specific lines discussed.
