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.
