> It seems that the operations are performed in the same thread as the invoker; if we happen to send multiple operations to the local node, these are performed in sequence, and in sequence with the remote operations. We should use an Executor for the local tasks.
> *Edit by Manik*:
> After discussing with Sanne and Vladimir, I am reopening this issue as it isn't really a duplicate of ISPN-1274.  This is more about being able to take a task and run the task, locally, using multiple threads (not just on a separate thread).  Essentially a lot closer to Fork/Join, but with the ability to run this on multiple nodes.  The degenerate case would possibly look a lot like the JDK's F/J, on a single node.
