I am still new to GAE, but could we not push an instance of DispatcherServlet into MemCache or the datastore?
Then when the application idles we can pull the instance back out of storage instead of creating a new instance. Is that not what Google is trying to say in their FAQ, "Share expensive initialization between JVMs. For example, put data which is expensive to read or compute into memcache, where it can be quickly read by other JVMs during startup."
