    Problem Text
    In connect test 1, the master program is supposed to connect twice
    to the same target address. But the function u_rcvaddr() uses
    static variables to hold the struct netbuf and struct sockaddr_in
    which contain the target address data, and u_rcvaddr() is called with
    a different address before the second t_connect() call. This results
    in the wrong sndcall address in the second t_connect(), and the test
    will timeout and fail
