while True:

async def app(scope, receive, send):
    if scope['type'] == 'lifespan':
        while True:
            message = await receive()
            ...

Seems to me it would block the entire server. If it's correct, can someone explain why?

[nggit]

It looks a correct pattern. And similar to the example in ASGI docs: https://asgi.readthedocs.io/en/latest/specs/lifespan.html

Seems to me it would block the entire server

No. Which the blocking things? The app() task will be just alive until shutdown. But it won't interfere server to create another app() instance for each request event.

It should be easy to verify this.
