Ug, semaphores are a horrible construct. I believe you can do the same
thing here with pthread_cond variables. I attached a small program that
uses pthread_cond and pthread_mutex to do interval times like this.

Note, another thing is, you can just have a global "end" variable that
can be set and checked (as I did in my program here).
