Code changing mChannelState is interesting.

        if (GOODBYE_MESSAGE_TYPE == aMsg.type()) {
            // :TODO: Sort out Close() on this side racing with Close() on the
            // other side
            mChannelState = ChannelClosing;
            if (LoggingEnabled()) {
                printf("NOTE: %s process received `Goodbye', closing down\n",
                       (mSide == ChildSide) ? "child" : "parent");
            }
            return true;

So there's some handy logging capability (if defined DEBUG), and they think
there's a possibility of a race.

(In case anyone is frustrated and wants to poke around)
