This doesn't work because "cores" are associated with physical dies
whereas dev.cpu currently counts logical CPUs (scheduling entities ie
Also note that kern.smp.cpus is the total number of logical CPUs. If
you have multiple multi-core processors then whatever.cores will be
different to kern.smp.cpus
Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
