9*0Sstevel@tonic-gate   * clean_exit() cleans up and terminates the program. It should be called
10*0Sstevel@tonic-gate   * instead of exit() when for some reason the real network daemon will not or
11*0Sstevel@tonic-gate   * cannot be run. Reason: in the case of a datagram-oriented service we must
12*0Sstevel@tonic-gate   * discard the not-yet received data from the client. Otherwise, inetd will
13*0Sstevel@tonic-gate   * see the same datagram again and again, and go into a loop.
