I use make on FreeBSD for running jobs with high levels of concurrency
(~100, or about ~300 if you count multiple concurrent make processes).
I've not benchmarked anything, but it would be a shame to remove
kqueue support because "it doesn't have a performance benefit" without
measuring it at the high end.
