DMR gave an amusing description of Ken's self-reproducing loophole bug done
years ago. As a user of (one of the) systems on which it got installed

extra code a function -- the tipoff was the item in the namelist that
never appeared in the source.
2) I doubt that anyone would have known what happened if Ken hadn't left

3) This occurred when one could seldom expect that one's old cc would compile
Dennis's newest cc source (due to continual bootstrapping) -- we always had
to grab both new source and new object. this helped the trap considerably.
