private Node resolveAndGetNode(String name) {

  Node node = null;

  // we depend on clusterMap to get a canonical node object
  // we synchronize this section to guarantee that two concurrent
  // insertions into the clusterMap don't happen (resulting in
  // multiple copies of the same node being created and returned)
  synchronized (clusterMap) {
    while ((node = clusterMap.getNode(networkLoc+"/"+name)) == null) {
      clusterMap.add(new NodeBase(name, networkLoc));
    }
