If it's only going to take you an hour to address this patch (or 8 to
address those other ones) then you spend a heck of a lot less time on
review for a patch of a given complexity level than I do.  I agree
that it's desirable to slip things in, from time to time, when they're
uncontroversial and obviously meritorious, but I'm not completely
convinced that this is such a case.  As an utterly trivial point, I
find the naming to be less than ideal: "poorman" is not a term I want
to enshrine in our code.  That's not very descriptive of what the
patch is actually doing even if you know what the idiom means, and
people whose first language - many of whom do significant work on our
code - may not.

Now the point is not that that's a serious flaw in and of itself.  The
point is that these kinds of issues deserve to be discussed and agreed
on, and the process should be structured in a way that permits that.
And that discussion will require the time not only of the people who
find this patch more interesting than any other, but also of the
people who just said that they're busy with other things right now,
unless those people want to forfeit their right to an opinion.
Experience has shown that it's a whole lot easier for anyone here to
get a patch changed before it's committed than after it's committed,
so I don't buy your argument that the timing there doesn't matter.
