[racket] Web server: Disable timeout?

Hm. Thanks for the websockets link. Is it possible to do that
with HTTP alone, as a fallback?

By COMET, do you mean where the client disconnects and reconnects
every so often? That's possible, and practical even, with the
existing timeout behavior in the web server. I'm just seeing if
it's possible to extend COMET so the client doesn't have to
reconnect.

Here's an example of a service that I'm aiming to reimplement
https://dev.twitter.com/docs/streaming-api/concepts#connecting
See section 6, "Connecting".
