some ideas:

- a view checks if the task is done, if so, shows the result. if not,
uses another template with the 'wait a sec..' message and a 'refresh'
HTML header that reloads the page after a few seconds.

- the 'wait' page starts with a javascript that does a periodic AJAX
call to check if it's done. when it's so, redirects to the 'result'
page.
