Err... don't do this like you did :) There are some "do's" and "don'ts" in the programming books and you've touched most of the "don'ts" with your code.
Use the scheduler: http://web2py.com/books/default/chapter/29/04#Scheduler You'll also most likely be using ajax to poll the database and check if the task has finished in order to make your front-end perform something. Once you have some code in place, don't hesitate to ask more questions if you get stuck. Sheduler has also been discussed a lot in the past, so the group's search will help you too.
