Issue running hypercorn as a task about hypercorn

[glasah]

I can get it working if I set

config.use_reloader = True

This is a really weird one, if I put the loop in a task and await the serve it works fine. When it does error it is a GeneratorExit being thrown somewhere, I think due to garbage collection, that triggers the error. As a workaround I suggest,

import asyncio

from hypercorn.asyncio import serve
from hypercorn.config import Config
from quart import Quart, request

app = Quart(__name__)


@app.route("/ping", methods=["GET"])
async def ping():
    return "pong"


config = Config()
config.bind = ["localhost:8080"]

async def foo():
    while True:
        print("Hello")
        await asyncio.sleep(1)

async def main():
    await asyncio.gather(
        asyncio.create_task(serve(app, config)),
        asyncio.create_task(foo()),
    ) 

asyncio.run(main())

With the latest master, this works for me,

import asyncio

from hypercorn.asyncio import serve
from hypercorn.config import Config
from quart import Quart, request, jsonify

app = Quart(__name__)


@app.route("/ping", methods=["GET"])
async def ping():
    return "pong"


config = Config()
config.bind = ["localhost:8080"]


async def main():
    finished = False

    async def foo():
        nonlocal finished
        await serve(app, config)
        finished = True

    asyncio.create_task(foo())
    while not finished:
        print("Hello")
        await asyncio.sleep(1)


asyncio.run(main())

With dbaf6a4, 354e7c8, and 19cbe37 being the crucial fixes.
