No, but when these "sources" as you call them are external data sources 
that I have to periodically check (have to -- there is no way to make 
these external contact my app when something changes), that is 
inherently a polling situation.

True; that just makes it easier.

I'm accessing a web service.

Same answer.  These services give you an answer when you ask for them; 
they don't come to you when a value changes.

Anyway, I think I have the answer I need 
(twisted.internet.task.LoopingCall), and I thank you all for it.
