No, it doesn't. It doesn't have any connect() calls or anything.

If you're using a flow graph, you use the scheduler automatically, you don't need to set it up or anything. Have a look at the file I recommended. If you feel you don't understand something, first read the introductory documents on the wiki, as well as http://gnuradio.org/redmine/projects/gnuradio/wiki/Simulations.
