> With the emphasis on JavaScript, there is an issue where a user on a slow connection interacts with the page before the page has fully loaded its JavaScript and run initializations. This can lead to client-side JavaScript exceptions, or server-side failures (when ordinary requests are sent to URLs that expect an Ajax/XHR request).
> The right solution is for Tapestry to provide a "pageloading mask", a div that masks the entire page from user input (and provides a loading image) until page initializations complete.
> The implementaton of this uses a <script> tag, with document.write, to introduce the mask element at the top of the page (so that non-JavaScript-enabled clients will be able to interact with the page to some degree).
> CSS animations are used to fade in the mask after a delay.  The presentation of the mask can be modified via CSS overrides. By default, it is black with 50% opacity.
