Not "yielded from" coroutine when using latest aiohttp with gunicorn and uvloop

[jnosal]

Environment

Python 3.6
Alpine Linux
aiohttp==2.0.1
gunicorn=19.7.1

Problem

After upgrading aiohttp to version 2.0.1 and running my application using aiohttp.worker.GunicornUVLoopWebWorker with PYTHONASYNCIODEBUG=1 I see following errors (or be it warning since they don't appear when asyncio debug is switched off):

<CoroWrapper Signal.send() running at /usr/local/lib/python3.6/site-packages/aiohttp/signals.py:38, created at /usr/local/lib/python3.6/site-packages/aiohttp/web.py:116> was never yielded from Coroutine object created at (most recent call last): File "/usr/local/bin/gunicorn", line 11, in <module> sys.exit(run()) File "/usr/local/lib/python3.6/site-packages/gunicorn/app/wsgiapp.py", line 74, in run WSGIApplication("%(prog)s [OPTIONS] [APP_MODULE]").run() File "/usr/local/lib/python3.6/site-packages/gunicorn/app/base.py", line 203, in run super(Application, self).run() File "/usr/local/lib/python3.6/site-packages/gunicorn/app/base.py", line 72, in run Arbiter(self).run() File "/usr/local/lib/python3.6/site-packages/gunicorn/arbiter.py", line 202, in run self.manage_workers() File "/usr/local/lib/python3.6/site-packages/gunicorn/arbiter.py", line 544, in manage_workers self.spawn_workers() File "/usr/local/lib/python3.6/site-packages/gunicorn/arbiter.py", line 611, in spawn_workers self.spawn_worker() File "/usr/local/lib/python3.6/site-packages/gunicorn/arbiter.py", line 578, in spawn_worker worker.init_process() File "/usr/local/lib/python3.6/site-packages/aiohttp/worker.py", line 238, in init_process super().init_process() File "/usr/local/lib/python3.6/site-packages/aiohttp/worker.py", line 38, in init_process super().init_process() File "/usr/local/lib/python3.6/site-packages/gunicorn/workers/base.py", line 131, in init_process self.run() File "/usr/local/lib/python3.6/site-packages/aiohttp/worker.py", line 46, in run self.loop.run_until_complete(self._runner) File "/usr/local/lib/python3.6/asyncio/coroutines.py", line 125, in send return self.gen.send(value) File "/usr/local/lib/python3.6/site-packages/aiohttp/worker.py", line 102, in _run handler = self.make_handler(self.wsgi) File "/usr/local/lib/python3.6/site-packages/aiohttp/worker.py", line 62, in make_handler self.cfg.access_log_format)) File "/usr/local/lib/python3.6/site-packages/aiohttp/web.py", line 224, in make_handler self._set_loop(loop) File "/usr/local/lib/python3.6/site-packages/aiohttp/web.py", line 116, in _set_loop self._on_loop_available.send()

for previous version of aiohttp (< 2.0) everything worked fine
