@pwendell BTW, yes, it works just as well if you just put `-T 1.5C` at the
end of your flags, and I agree that this is the right way (unless this were to
become a standard flag in the build, which I wouldn't recommend without testing
beyond my own). There's no reason to invent another syntax for enabling
threading.
If you're interested, I will take some time this week to write up a
paragraph for the docs and send a PR in case others are interested. (To me,
shaving ninety seconds off a ten-minute build is a worthwhile speedup, but I
won't waste my time unless you think you'd want to add it to the docs.)
