 Paste ist not asynchronous, and keeping queue control in web
application is bad solution.
 You can try this:
 - load a task to database
 - web application will redirect to a checking location, where will be
current status of this task
 - run a controller process which wolud check periodically for new tasks
   - if there is a new task, controller will spawn a worker for it
   - worker will do the task and update task record in database
 - checking location will inform that task is done
