The server holds on to all the websockets in one big async thread, then
calls your Django code synchronously whenever an event happens on the
socket.

You shouldn't do this, use the normal worker pattern, there's lot more than
just receive_many to do

You have to send it to a custom channel with the reply_channel of the
socket, have a worker listen on that channel, and when it is done send
information back to the reply_channel.
