Answering the last question first - I don't think so. Something may
indeed want doing here beyond what we already have, and it may well
be precisely what Andrew is proposing, possibly just with extended
descriptions and/or comments. My confusion about patch 3 is that it
(a) claims behavior in turbostat that I can't locate and (b) implies
(describes) behavior of code that I find entirely unexpected (as in:
not making sense to me).

And I'm sorry: Not all of the words are of one syllable.
