By the way, in case it wasn't clear, we have a disagreement (and perhaps
a misunderstanding) only about the meaning of the original code posted.
You believe it is allocating many integers.  I believe it allocates
only a single one.  Perhaps one of us is wrong.  I hadn't read the code
in great detail, and still haven't, and perhaps that's my mistake.
Depending on your reply, I'll actually go back and look at it closely
and perhaps execute it myself and see the result (in terms of the list
produced, not in terms of the memory consumption).  Maybe you will
do the same and we'll identify which of us is mistaken...
