I'll happily admit to not being an expert here :)

However, I thought that the concept of cpusets was that if you
attempted to set affinity outside of your cpuset, that would silently
fail. I assume that the reason that libnuma didn't want to set outside
of it's own affinity mask is to avoid such a silent failure?

Also, I question the Real World(TM) prevalence of cpusets.

Not sure if I'd call it a bug since it was intentional, but sure would
call it an unexpected change in behavior :)
