> This jira is intended for code sharing. I'd like to have a BlockSender which
> is resposible for reading a block from a disk and writing it to an output
> stream, and a BlockReceiver which receives a block from an input stream,
> writes it to a disk, and possibly writes it a mirror ouput stream to support
> pipeline writes. Block sender and receiver code is independent of any block
> IO protocols so it could be shared by block transfer, block write, block
> read, and future block replacement introduced by data node rebalancing.
