> HDFS-959 suggests that the MAX_PACKETS variable (which determines how many 
> outstanding data packets the DFSOutputStream will permit) may have an impact 
> on performance. If so, we should make it configurable to trade off between 
> memory and performance. I think it ought to be a secret/undocumented config 
> for now - this will make it easier to benchmark without confusing users.
