Great and you really believe this accelerates a program? Starting a
thread takes a lot of time and such loops are usually memory throughput
bound.
OK, I should not have used 10 as the element but 1000000 :). And of
course it makes more sense if a more complex calculation is to be done
in each loop. But exactly this issue (lots of independent calculations
in parallel) is a widely seen task (e.g points in physical fields).
Of course the RTL is not supposed to start a thread for each of the loop
runs but assign a number of them to a couple of threads.
