that problem may well be macOS specific: since at least macOS 10.13
(maybe even 10.12; cannot currently tell for certain) make -jN check
times on my Mac mini skyrocketed with between 60 and 80% system time.
It seems this is due to lock contention on one specific kernel lock, but
I haven't been able to find out more yet.
There's no such problem on other targets, not even e.g. on Mac OS X 10.7.
