> The is a bug in the Sort function of graph.cc, which would push one node into
> the 'tmp' queue for multiple times if this node has multiple source nodes.
> Solution, check for every node if it is already in the queue before pushing
> it.
> When it is not in the queue, then push it. Otherwise do nothing.
