However, since the socket timeout exception will be classified as type:
`unkonwn exception` in thrift, rather than `conn timeout` in reality, the
result will not be `conn timeout` still. But If we use `conn timeout` msg to
cover the `unkonwn exception`, that may hide the msg of other `unkonwn
exception`s, should I enhance it further @freemandealer ?
