Thank you Jason.  Yes, it would be helpful.  And I had wondered if that 
was possible.  Cheers.

FWIW: I am now testing the script using the ports/sysutils/daemontools 
utilities.  That seems to be working well so far.  I will be writing a 
daemontools article for the Diary and will post the URL here for feedback 
before I make it public.
