Another advantage is that the magic number 1024 (128 bytes of CPU bits)
is gone, so testing on smaller machines is possible.

Well, I did that (144 CPU cores, detected set size 192 bits), and it
turns out that my pthread test case is completely broken. :-(

Here's a new one.  It tries to check that the active CPU set returned by
the kernel has not been truncated, and that threads are not scheduled to
CPUs outside the set.
