I am implementing a google app engine web service that crops very large images. However, cropping can take well over 30 seconds which is (for some reason) a real problem for app engine. To avoid this I have implemented Taskques. However, once the image has been cropped within a Taskqueue I would like to update the page that made the original request, showing to the user the newly cropped image.

So my question is, is there some sort of Taskqueue callback? or do I just have to keep polling a the server to see if my Taskqueue has been finished?
