    Look that this is not true. If one core is not running any task, the idle
    task (if not polling) does "hlt" and the "what they call Fetch And
    Deliver" engine will be dedicated to the other core. Also, because the
    halted core not not issue any op to the execution engine, full resources
    will be available for the running task. There are many docs available
    inside the Intel developer web site that explain this.
