I just committed a method gt_node_stream_pull() which simplifies many
calls to gt_node_stream_next().
In fact, most calls to gt_node_stream_next() in the tools could be
simplified by calls to gt_node_stream_pull().
Please see the API documentation and the implementation of
gt_node_stream_pull() for details.

Any takers for the corresponding bindings?
