//  Eliminating sorry_about_global_temp inititialisation. This don't work
//  in combination with NewsCache. My idea is: initializing the classes with (0)
//  and in the second step call ios::init (sockinetbuf *) and iosockstream::init ...
//  The constructors of isockunix, osockunix and iosockunix are changed.
