I agree, but like I said earlier, this was the easily available ready made
application I found. Do you know of any other highly threaded micro benchmark?

The order was different each time. I suspect that when we have too many threads
all exiting at once and they are all running in parallel, I don't know if we can
have ordering or predict the order in which threads exit.
