Distinction noted.  It was not entirely clear to me which case applied to 
my code:

         1) N objects all having reference counts of 0 or
         2) N objects with N-1 references counts of 1 in
            a chain with 1 object having 0 references.

IOW, I was not clear which model applied to my situation.  I was abetted in 
not having a clear picture of this because memory I expected to be returned 
to OS was not returned. I was holding open the possibility that the 
cyclic-reference collector might apply.

Yes, Cool!  Great stuff.
