在Tornado中为使用@run_on_executor修饰的函数设置超时条件的最佳方式是什么？

from tornado.ioloop import IOLoop
from tornado.gen import TimeoutError

from concurrent.futures import ThreadPoolExecutor

executor = ThreadPoolExecutor(max_workers=4)  # 假设线程池最大工作线程数为4

@gen.coroutine
def my_function():
    try:
        yield executor.submit(my_blocking_function)  # 使用executor.submit来执行阻塞函数
    except TimeoutError:
        # 处理超时异常
        pass

@gen.coroutine
def my_function():
    try:
        yield gen.with_timeout(timedelta(seconds=5), executor.submit(my_blocking_function))  # 设置超时时间为5秒
    except TimeoutError:
        # 处理超时异常
        pass

def timeout_callback():
    # 超时回调函数逻辑
    pass

IOLoop.current().add_timeout(timedelta(seconds=5), timeout_callback)  # 添加超时回调函数
