Oh, you're right :-) I only checked ncpus (1), not the final result.
It works because CPU_ALLOC_SIZE() rounds the size using
sizeof(unsigned long) (64 bits on my CPU). So CPU_ALLOC_SIZE(1)
returns 8, and sched_getaffinity() takes the size of the set in bytes,
and not the number of CPU.

sched_getaffinity(0) returns {0, 1, 2, 3, 4, 5, 6, 7} with ncpus=1 and
setsize=8.
