[Doug Farrell] Don't mind the PITA at all, I actuall did read the source code and just didn't 'get it' so much. In my case the function that LoopingCall was passed was actually doing the work, not returning a Deferred. However, I'm going to look into doing that.

In my sample code the someFunction() code was actually doing the work I wanted, not creating a deferred as your sample shows. However, I'm going to try that out and give it a run. Thanks!
