[Twisted-web] stopping LoopCall and check if running

[Terry Jones]

Hi Stephan

I wont try to answer your question, but this error:

>        result = g.send(result)
>   exceptions.AttributeError: 'NoneType' object has no attribute 'send'

is what you see when you decorate a function with @inlineCallbacks but
don't have any yields in the function (i.e., it doesn't return a generator
object). You should definitely find & fix that problem.
