You specify a sleep time of 10000 msec = 10 sec and your program takes 
2min+42sec = 162sec to execute. Therefore one would assume that some of 
the threads finished before others started, thus failing to stress the 
limits of thread allocation by the system.

Why don't you try an insane timeout, like 900000;
