Threading in Mathematica<http://documents.wolfram.com/mathematica/functions/Thread>has
nothing to do with threading in the operating system sense.
RTFM <http://en.wikipedia.org/wiki/RTFM>;
Threading is just an inside-out sort of map function, where f({a,b}) => {
f(a), f(b) }
And yes, map, makelist, etc. etc. have a natural parallel structure (as long
as there are no side-effects). Taking advantage of it is another matter....
