Asynchronous ORM access

[D3f0]

As far as I'm concerned Django ORM does not support asynchronous operation, so https://github.com/peterbe/django-sockjs-tornado/blob/master/example/project/chat/sockserver.py#L19 would block the socketserver process in your example.
I don't know if tornado has something similar to Twisted's deferToThread in its tornado.gen package.
