Visible to whom and how? The other images terminate execution too. They 
cannot look at the data. Your image terminated too. Of course, your 
network monitor may tell something went down the wire, but the program 
cannot tell. And so it does not matter---if it is not visible to a 
legal program it simply is not specified by the standard.
