You can start it from the environment.rb, yes, but you need to remove
the semaphore file before starting he mongrels.
This cannot be done from within the environment.rb because each
mongrel starts its own process.
I want to have the scheduler inside my Rails application.
I could run it using script/runner but then I have to maintain another
process.
This way the scheduler is stopped when I stop the application and vice-
versa.
