[Twisted-Python] Simple way to halt all timers?

[Russell E. Owen]

Is there a simple way to cancel all Twisted timers (pending 
reactor.callLater calls)?

The reason I want to do this is to clean up a unit test without getting 
"dirty reactor" complaints. 

The system is a server that will rarely be shut down and does not have 
to shut down gracefully (i.e. I don't care if the reactor is dirty). But 
I want the unit tests to run cleanly, so for now I've been keeping a 
reference to each timer that I start, so my test cleanup code can 
manually cancel it. It's a lot of fuss, and makes timers harder to use 
than they should be. I admit that in many cases I need a reference to 
the timer anyway, since I may have to cancel it for reasons that matter 
to the server. But I hate having to do it for *every* timer. If there 
was a simple way to tell the reactor to cancel any outstanding 
"callLater" calls, the code would be much cleaner.
