You don't really need one..

Simplest way to handle this would be for the web page to kick off the 
model running in another process, and then immediately display a web 
page that says "Please wait, model running.."

That page then either uses javascript or a http-refresh mechanism to 
check back every 30 seconds to see if the model is ready yet.
