I think we do not have to worry, and the reason is that the justification for 6129c930 is simply wrong. As I did not find the patch series discussed here to pull and test, I repeated the timing tests with t7610-mergetool.sh with and without 6129c930 reverted, and the difference is only in the noise. The reason t7610 takes so long on Windows looks more like a consequence of the 10,000 processes that it spawns. It is a mystery to me how I came to the conclusion that the change in 6129c930 would make a difference. :-( -- Hannes
