OutboundTcpConnection in 1.0.0 may stop working

[liangfeng]

In cassandra1.0.0, I found that OutboundTcpConnection will throw
RuntimeException when it encounters an IOException(in write()) .In this case,
OutboundTcpConnection as a thread will stop working--do not send any message to
other nodes.
This is not reasonable,isn't it?
