> and latency of recovery. 
> In addition to the existing HDFS checkpoints,1) the tasks log outgoing 
> messages to local filesystem for each superstep (See disk queue). When a task 
> fails, 2) it reverts to the last checkpoint. 3) Other tasks re-send messages 
> sent to failed task at each superstep occurring after the last checkpoint.
