协程是否正在等待asyncio.Event设置为保证每次设置事件时都会得到通知？

Event.set（）和Event.clear（）都不是可等待的。因此，可以设置和清除事件，而无需将控制返回到循环。因此，我猜调用set（）和clear（）不会将事件通知侍者。我发现确保通知服务员的唯一方法是添加asycnio.sleep（0），以将控件强制返回到set（）和clear（）之间的循环。但这对我来说看起来很丑。

这里是一个例子：

NUM_EVENTS = 1000
NUM_WAITERS = 1000

import asyncio

async def waiter(event,id):
    print('waiting for it ...')
    for i in range(NUM_EVENTS):
        await event.wait()
        await asyncio.sleep(0)  # might be dropped by affects order
        print(f'... {id} got {i}')

async def main():
    # Create an Event object.
    event = asyncio.Event()

    # Spawn a Task to wait until 'event' is set.
    waiter_tasks = []
    for i in range(NUM_WAITERS):
        waiter_tasks.append(asyncio.create_task(waiter(event,i)))

    # Sleep for 1 second and set the event.
    await asyncio.sleep(1)
    for i in range(NUM_EVENTS):
        event.set()
        await asyncio.sleep(0)  # leaving this out will result in the waiters only receiving the event once
        event.clear()

    # Wait until the waiter task is finished.
    await asyncio.wait(waiter_tasks)

if __name__ == '__main__':
    asyncio.run(main())

在第31行上省略asyncio.sleep(0)会使服务员仅接收一次（而不是1000次）事件。

但是如何干净地做到这一点？
