Thank you Chet for this pointer!

It was a work that I was personally not previously aware.  I am
familiar with his other work such as his seminal paper, How to Write a
UNIX Daemon by Dave Lennert but this one you reference, A System V
Compatible Implementation of 4.2BSD Job Control by David C. Lennert,
had escaped my notice thus far.  I have only been able to skim it
briefly but it appears to be typical of the high quality of Dave's
works.  I have already learned several things from it.

engineers and programmers too! :-)
