Heh, let's try not to waste duplicated efforts by being silent next
time, OK? Winning such a race by 5 minutes does not buy us much.
I wish we had some type safe way to say "This uint and the other

pending array was not transferred to the commit list used by the
What's interesting still is that

git checkout master
does not exhibit this problem in the same repository.
