The DeferredDispatcher is a way to get around the 30-second limit for App Engine requests. We don't want spin-up to be a "show stopper", and we want every request to have a full 30 seconds to do "real work". We added this to appengine-rack 0.0.7, so folks won't need an additional require. The DeferredDispatcher works by using redirects to break up a loading request into 3 parts.

1. initialize the jruby runtime and jruby-rack
2. require the framework, and create a new dispatcher
3. process the real request, with a full 30 seconds

We are inside jruby-rack, so obviously the runtime and Jruby-rack have initialized, so first we set @runtime to true (from nil) and redirect. Next pass, we notice that the @rack_app is nil, so we require the framework (which can take some time) and create a new dispatcher (these have been passed in as a hash) and redirect. In the final pass, we hand the environment to the dispatcher, to do the original "work" of the request.
