Hi Beyers,

Thank you. It works like charm, and fits to my goal. One more question
is whether it uses cpu affinity? From my analysis, there is no such
thing. I have to fix each thread to each core. Does Click have CPU
affinity option somewhere? Otherwise, I will add that for my purpose.

Thanks,

Jinho
