Visible to whom and how? The other images terminate execution too. They=20
cannot look at the data. Your image terminated too. Of course, your=20
network monitor may tell something went down the wire, but the program=20
cannot tell. And so it does not matter---if it is not visible to a=20
legal program it simply is not specified by the standard.
