Sinatra/Rack Sleep until Response Ready (like Exchange ActiveSync)

Question

I'm wanting to do a lightweight push-style HTTP response in my existing Sinatra web app. Is there any mechanism that allows me to not respond to an HTTP request and keep the connection open until I wake up the connection at a future time?
