Why not just use twisted.internet.task.LoopingCall?

I overlooked using task.LoopingCall in conjunction with creating a request handler tasklet. I tried and it works nicely. And LoopingCall is faster too. Sweet! With the possible need to add critical sections to stuff like add/remove reader/write, this means I can leave the reactor alone. This is good. In the past, I used task.LoopingCall to solve an earlier problems. I guess I threw the baby out with the bath water. Thanks alot!
