Yes, `num_processors (NPROC_ALL)` is an equivalent that would work.

Correction to my previous mail which mentioned CPU affinity being an 
issue, that's only used for `NPROC_CURRENT`.

If the additional complexity of GNULib's `lib/nproc.c` isn't viewed as a 
major down-side (~279-SLOC ~27-SLOC from the patch I submitted), both 
can work.
