Right. So in that case I would push the sched_getaffinity()
down into num_processors in gnulib.

Whether to drop the --installed (and consequently --available)
options to nproc, is debatable. If we leave it in then gnulib
would need a method to select between them.  Let's leave it
selectable for now unless others think it's superfluous.
In any case num_processors should return the "available"
count by default.

Pádraig.
