  scx_barrier.cpp -- This example demonstrates the proposed scx_barrier class
             that provides execution synchronization between threads. Each
             thread in the "thread pool" of an scx_barrier object instance
             waits on the scx_barrier object instance. When all the threads
             in the thread pool are waiting, they will all be dispatched.
