[Twisted-web] Question regarding callLater() and service creation

I'm creating a service using Twisted. It has nothing to do with networking (I know that Twisted is an event-driven networking engine... stay with me here :). It's simply polling a database every 30 seconds. I'm using callLater() once the work has been completed. My question is does the reactor spawn a new thread once the callLater() timeout has been reached? If so, this would mean that the work being done may be effected by the GIL, correct?
I may make more services like this where Twisted is used to create the service. These services may do a lot of heavy lifting... and may have nothing to do with networking. However, I like the fact that Twisted gives me a base for creating services. I also like the fact that if I do any network related services I'm using the same lib... which will use the same method to launch the service, etc.
Even with all of these pros I still feel like I may be using the wrong tool for the job. Maybe I answered my own question... for non-network related services, services that will do a lot of heavy lifting, etc. fork a process (there are plenty of classes out there that daemonize scripts easily enough) and use Twisted for all event-driven networking related services.
I'd be interested to know what you guys think. Thanks in an advance!
