I wonder if the phrase "As for $$," is part of the confusion here. It
could be read to mean either "In the same manner as $$, ..." or as
"Conversely, $$ ..." (the former being the correct interpretation).
Still mulling over possible rewording (at the very least change "for"
to "with" in that phrase). Suggestions that don't try to explain unix
process hierarchy management in detail, are welcome.
