> 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.
