> Will it make sense to say "I don't want hyper-threads" ?

Not sure I remember correctly, but I believe one motivation behind avoiding 
"hyper-threads" and other virtual cores was that while they improve slightly 
the performance, they also increase the peak memory requirements: using 
heavyweight_hardware_concurrency() seemed like a good default tradeoff for most 
end-users.
