> DFSClient with hedged reads enabled will often close previous spawned 
> connections if it successfully reads from one of them. This can result in 
> DataNode's BlockSender getting a socket exception and wrongly marking the 
> block as suspect and to be rescanned for errors.
> This patch is aimed at adding windows specific network related exception 
> messages to be ignored in BlockSender.sendPacket.
