The tasks returned by shutdownNow haven't begun execution, so there's no need to cancel them.

Is there some handy delegation pattern available, such as found on Executors, to wrap an ExecutorService implementation such that ExecutorService#shutdownNow() cancels each task in the returned list?  While this might not always be want people want to do, it does seem to be a very common pattern.
