// This example shows how to render pages that perform AJAX calls
// upon page load.
//
// Instead of waiting a fixed amount of time before doing the render,
// we are keeping track of every resource that is loaded.
//
// Once all resources are loaded, we wait a small amount of time
// (resourceWait) in case these resources load other resources.
//
// The page is rendered after a maximum amount of time (maxRenderTime)
