Simple example code that performs some 'blocking' function inside a worker thread. The boss creates a number of tasks threads of different types which will wait until the boss updates their parameters and then 'starts' them on whatever particular type of task that have been given. The boss at some later time will block on waiting for the worker threads to finish their tasks. Once the worker has finished their task it will hold again until the boss re-starts them.

The worker threads are created and destroyed at the start and end of the applications life time. Usage its usage is very similar to 'create'/'join' without the overhead of having to create a new thread each time work is needed.
