Re: go124 not respecting MAKE_JOBS
I ran the build of go124 with MAKE_JOBS from $(seq 1 5). Interestingly
3 was fastet, but really 2 or higher were the same. I ran a script to
capture load every 5s and find the max. (Yes, I know that's kind of
bogus.)
It seems that parallelization goes roughly as the square of MAKE_JOBS,
suggesting go runs GOMAXPROCS proceses each of which use that many
threads. And that this build runs out of parallelization around 10.
