Can I start and stop slow-motion workers from my Rails application?

Question

I have an application that can benefit from delayed_job and some background processing. The thing is, I really don't need / need delayed_job workers to work all the time.

The application works in a shared hosting environment and in different places (for different users). In addition, the application does not receive a large amount of use.

Is there a way to start and stop processing tasks (either using a script task or a rake) from my application only after certain actions / events?

system "cd #{Rails.root} && rake delayed_job:start RAILS_ENV=production"

If you go to stop the employee, you are given a PID. You can just kill -9 PID if all else fails.
