@raix @syrusakbary when is the next release? I'm hitting the same problem. I can patch it on our end for now, but would rather have an official release :)

@raix
[this is the issue]
opened one in graphene-django to see if someone can help me
graphql-python/graphene-django#452

[earlier attempt]
This was an earlier attempt to get it to work with promise as a return type

I think this might be helpfull when the event loop is already running ..

[japrogramer]

Here Instead of calling run_until_complete it could call a friendlier method to those who already have loop running ..

async def wait_until_finished(self):
         # if there are futures to wait for
       if self.futures:
       while self.futures:
           # wait for the futures to finish
           futures = self.futures
           self.futures = []
           self.loop.create_task(futures)

Hi, I think this code here have some issues
We should give the timeout for the run_until_complete one right?

Or if the task not finished or something else wrong, the task just hang there, the self.futures will always be True, and stuck here.
Then the request is always pending.
