With ThreadPoolExecutor, you have the API to accomplish this in a couple of

1: tpe.shutdown(); tpe.getQueue().drainTo(submitted);

The above is similar to what shutdownNow does.

2. Another way would be to wrap the tasks on submission with a Runnable
that checks isTerminating() and punts if it is true.
