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.
