signal() does not _emit_ a signal, it sets up a handler for a specific
signal, in this case SIGINT, so that the ob_sig_int function is called
when you press control-C on the command line to stop the echoserver. It
then cleans up in that function and returns a FAILURE error code to the
system. (This is just guess work mostly, I don't know why it was added
originally)
