I figured out why my processes were not "exiting".  It just turned out
that they hadn't finished running.  Doh!  I should have left the print
statement when the head of the ring received the token back and exited.

I'd still be interested in any feedback on the code as I'd like to make
sure I'm doing things the "right way".
