The docs don't state what will happen to inputStream and outputStream
in the event of a failure (to bad it isn't stated). So you can't
safely depend on what the implementation will do since it isn't
specified. In a situation like that I would initialize them to nil
before sending that message.

Additionally I would query the status of the returned stream to
validate the state is as you expect (see -[NSStream streamStatus]).
