    Yeah, I have to say that I particularly don't like patch #1. It's some
    rather nasty complexity for dubious gains, and holding the lock for
    longer times might have downsides.

    And the numbers seem to not necessarily be in favor of patch #3
    either, which I would have otherwise been predisposed to like (ie it
    looks fairly targeted and not very complex).

    #2 seems trivially correct but largely irrelevant.

    So I think this series is one of those "we need to find that it makes
    a big positive impact" to make sense.
