If you want utc to hang up the phone by killing cu, stick the
following at the end of utc:

	sig = signal(SIGTERM, SIG_IGN);
	kill(-getpgrp(), SIGTERM);
	signal(SIGTERM, sig);

You will have to make sure that the pipeline is not running with
the process group of its invoker, unless you want to kill the
invoker as well. Calling it from cron works fine.
