Как победить гонку в Pool при выводе?

 import multiprocessing as mp 
import time 
 
 
def foo_pool(x): 
    time.sleep(2) 
    print(f'Task {x} executing with {mp.current_process().name}', flush=True) 
    return x * x 
 
 
result_list = []

    for i in range(10): 
        pool.apply_async(foo_pool, args=(i, ), callback=log_result) 
    pool.close() 
    pool.join() 
    print(result_list)

    apply_async_with_callback()
