How do the JSON[0] and raw text[1] streams work? Doesn't that require there to be a thread running on the server for every connected client?

How does that not become a slowloris attack? [2]

Yes, subscribing requires connected clients to keep a connection open. I've tested this with many many thousand sockets and it seems to scale so far.

Additionally I limit the number of subscriptions per IP address.

So far so good.
