There are a few possibilities here -- pfdCleanTree will remove
pfGroup nodes (or derivatives) with 0 children; but what I'd really
suggest is taking a close look through the pfdCleanTree code itself
(shipped in /usr/share/Performer/src/lib/libpfdu/pfdCleanTree.c) to
see the cause of your undesired optimization. You could then make
modifications accordingly..
