I take the code I need to run separate from rails and set it up as a system daemon. I put all of these in my lib/standalone/ 
directory. Example:

/var/www/myapp/lib/standalone/report_generator

/etc/init.d/report_generator start|stop|restart

My rails app communications via Unix sockets to my report_generator.
