I am pretty sure my setup is closer to what mod_fastcgi calls "dynamic". Apache is in charge of starting and stopping the application instances based on load, and won't do so until the first hit to the app.
In practical terms though, the monitoring scheme we've got here should ensure that the "dynamic" app is always up and so I haven't looked at a more static-ish setup. If you do find out how to do this with mod_fcgid I'd be interested to hear about it.
