socket after sending the message without being interrupted by an exception,

look like when it's not catched), we add a potential command line argument
to the server, asking it to cheat and to not open its port within the search

-\dontinclude 08-exceptions.c
+\don'tinclude 08-exceptions.c
\skip strcmp
\until gras_socket_my_port
\until }
