How many people who regularly build Emacs have 2 cores?
And I don't think it's true that -j4 on such a system will be slower,
certainly not significantly slower. I build my Emacs with -j8 on a
system with 4 cores all the time, and never saw any slowdown.
Anyway, it isn't worth an argument, so I will now bow out.
