Constraints:
* Threads 0, 1, and 2 should proceed to complete their work
as soon as possible after they are created.
* Thread 3 must wait for threads 0 and 1 to finish before
thread 3 begins its work. However, thread 3 should begin
and complete its work as soon as possible after threads 0
and 1 are finished.
* The constraints for threads 4 and 5 are like those for thread
3, except that thread 4 waits for threads 1 and 2 to finish
before starting, and thread 5 waits for threads 0 and 2.
Also, each child thread increments the counter called
thrds_finished just before exiting. (Note that access to
this counter is a critical section problem.) The mother thread
reports the value of thrds_finished just before the program stops.
