Follow-up on #318
Some of newer Intel CPUs have 8 P-Cores and 16 E-Cores, so only the first third of CPU cores are P-Cores. Older generations have a higher ratio of P-Cores than that. So, for now,
$(nproc) / 3 - 1seems like an easy way to pick a P-Core whose index is reasonably large. See also #318 (comment) for why we're not using the first core.
