Instantiates a fully loaded, configured instance of a Tapestry page. This is a recursive process,
since part of loading a page is to load the page elements for the page, many of which are
components. Further, in some cases, the full component tree is not identified until after each
component's template is loaded. Because this is an expensive process, loaded pages will be used
for many requests (on behalf of many different users) and will be pooled between requests.
