+           If you use the <a href="dlib/threads/threads_kernel_abstract.h.html#create_new_thread">create_new_thread</a> function
            to create your threads then you receive the benefit of the dlib thread pool.  This pool enables the create_new_thread
            function to spawn new threads very rapidly since it draws threads back out of its thread pool when the pool isn't
            empty.
