Question about this: do the CPUs in the list correspond to the Linux virtual 
processor IDs?  E.g., do they correspond to what one would pass to numactl(1)?

Also, a minor quibble: it might be a little confusing to have --bind-to cpuset, 
and then have to specify a CPU list (not a CPU set).  Should it be 
--cpuset-list or --cpuset?
