Heh. What odds do you give it that the processor will be running on a
different core by the time his script has IDed the core? Or maybe even
cycled back again?
But, I guess if the OP's purpose is just to prove that scripts are not
confined to a single core, I guess it doesn't matter. (I can't say
that I can think of any other reason for the question, now that I
think of it. Hmm)

Be careful where you see conspiracy.
Look first in your own heart.
