Neat, though the intervals between executions of the child process seem
to be a little random (Lenovo T440 running Fedora 25). Running

     watch -n 1 date

displays the date/time with intervals of one or two seconds and the delay
doesn't always agree with the displayed interval. That said, it seems a
lot more regular with a 5 sec interval.
