将gunicorn与asyncio结合使用时，我如何屈服于另一个请求?

我正在尝试将Gunicorn中的gaiohttp工作者与我正在通过以下命令开发的Django应用程序配合使用:

I'm trying to use the gaiohttp worker in Gunicorn with a Django app I'm developing with the following command:

gunicorn -k gaiohttp -b localhost:8080 myproject.wsgi

我的最终目标是能够同时处理请求-即让一名gunicorn工作人员并发处理多个请求.有一些I/O绑定操作会使这些请求变慢.

My ultimate goal is to be able to process requests concurrently - i.e. have 1 gunicorn worker process multiple requests concurrently. There are I/O bound operations which makes these requests slow.

我知道在处理请求时已经在运行事件循环:

I know an event loop is already running when I'm processing a request:

class MyView(View):

    def get(self, request):
        loop = asyncio.get_event_loop()
        loop.is_running() # True
        ...

问题:

1. 如何在视图代码中执行acodeio.sleep(10)中的 yield之类的操作?

class MyView(View):

    def get(self, request):
        # Raises AssertionError: yield from wasn't used with future
        yield from asyncio.sleep(10)

@asyncio.coroutine
def simulate_work():
    yield from asyncio.sleep(10)

class MyView(View):

    def get(self, request):
        # This runs simulate_work(), however, it doesn't block 
        # the response is returned before simulate_work() is finished
        loop = asyncio.get_event_loop()
        task = loop.create_task(simulate_work())

@asyncio.coroutine
def simulate_work(future):
    yield from asyncio.sleep(10)
    future.set_result('Done!')

class MyView(View):

    def get(self, request):
        future = asyncio.Future()
        asyncio.async(simulate_work(future))
        loop = asyncio.get_event_loop()
        # Raises RuntimeError: Event loop is running.
        loop.run_until_complete(future)
        print(future.result())

很明显，我对asyncio或gaiohttp不太了解.

Clearly there's something I'm not understanding about asyncio or gaiohttp.

如何为当前请求提供 asyncio.sleep(10)阻止，但不能阻止gunicorn处理其他请求?

How can I have asyncio.sleep(10) block for the current requests, but not block gunicorn from processing other requests?
