             Summary: Allow DistributedExecutorService to control shutdown of given local ExecutorService
                 Key: ISPN-2464
                 URL: https://issues.jboss.org/browse/ISPN-2464
             Project: Infinispan
          Issue Type: Feature Request
          Components: Distributed Execution and Map/Reduce
    Affects Versions: 5.2.0.Beta3
            Reporter: Vladimir Blagojevic
            Assignee: Vladimir Blagojevic
             Fix For: 5.2.0.CR1



Constructors that receive a thread pool from clients not shut it down on stop: it's a good rule of resource management for the creator of the resource (thread pool for us) to manage the shutdown as well.
So here's how I think this can be solved:
1. Add a new Ctor that besides the pool also has a flag to allow us to take ownership of the pool (i.e. we'll destroy it when the DistExec is shutdow)
2. leave the current constructor as it is, make it internally invoke 1. with takeOwnership=true (this would preserve backward compatibility)
3. amend the executor to only shutdown the thread pool if it has ownership
4. document the threadpool ownership in all constructors
