Is each child generating his own GUI? I would expect to "ssh -X -Y server" and get the output thereto. Forwarding just DISPLAY would only work with a direct allowed connection via "xhost +". As each "ssh" to start a slave task might get a different entry for DISPLAY otherwise, depending on the free display ports, so forwarding localhost:10.0 will most likely not work.
