[racket] Web server: Disable timeout?

Michael, perhaps you're interested in Web Sockets.  They're a better fit for what you're trying to accomplish.  http://docs.racket-lang.org/net/websocket.html?q=websocket

Alternatively, you might try to implement a COMET service, and use long-polling.  This is a hack to emulate web socket style two-way communication.
