  That is correct and that is what happens.  In the package you use, the
sleeps are not preempted and happen sequentially, running each thread
either when it is created or when the join is done.  With thread packages
that preempt the sleeping thread, all of the sleeps happen over the same
second so once the join on the first thread finishes the others are also
done and can be joined immediately.
