Hm, this sounds like an interesting and important conceptual aspect of the way 
FreeSwitch works which I suspect I haven't fully "got".

Can you point me at the documentation which explains this, for people who are 
more used to procedural programming, and show how we should be thinking about 
FreeSwitch dialplans instead?

I'm certainly keen on using FreeSwitch in as efficient a manner as possible :)
