The provided code seems to be working correctly and does not contain significant irregularities or optimizations needed at this time. However, if you have specific concerns about performance, scalability, or maintainability related to handling events in hand_event_node_result, here are a few points to consider:

1. Data Explosion: If content contains a large amount of data, it might lead to memory usage increasing rapidly. Consider optimizing how the content is being handled.

2. Asynchronous Handling: Since the method is asynchronous (future), ensure that any heavy work associated with handling the result does not block other operations. This can include checking if there are any dependencies on previous results before proceeding.

3. Error Handling: Add error handling around critical sections where exceptions could occur, such as when accessing the current_node. Using try-except blocks will help manage crashes gracefully.

Here's an example of how you might add more robustness:

def hand_event_node_result(self, current_node, node_result_future):
    runtime_node_id = current_node.runtime_node_id

    try:
        real_node_id = current_node.runtime_node_id
        child_node = {}
        view_type = current_node.view_type
        
        # Ensure context remains synchronized during processing
        with self.context_lock:
            content_data = handle_large_content(content)  # Placeholder function
            child_results = process_children(current_node.up_node_id_list)
            
            response_payload = {
                'node_type': current_node.type,
                'runtime_node_id': runtime_node_id,
                'view_type': view_type,
                'child_node': child_node,
                'node_is_end': node_is_end,
                'up_node_ids': [result['upNodeId'] for result in grand_child_results]
            }
        
        # Send the final payload asynchronously
        future.add_done_callback(lambda f: send_response(f.result()))
    
    except Exception as e:
        print(f"An error occurred while handling event: {e}")

In this example, we've added basic error handling using try-except and ensured thread safety with a lock (context_lock) to prevent concurrent modifications to shared resources like self.context. The handle_large_content and process_children functions should be tailored based on your actual use case, allowing you to optimize them further for better efficiency.
