Title: Send Task results through the block manager when larger than Akka frame size (fixes SPARK-669).

This change requires adding an extra failure mode: tasks can complete
successfully, but the result gets lost or flushed from the block manager
before it's been fetched.

Thanks Josh for writing the original version of this patch!
