There are two problems with this code. First, under the thread_ref design, 
there is no boost::thread class:

thread_ref thread1 = create_thread( thread_functor_1 );

Second, create_thread makes a copy of thread_functor_1 and runs the copy, as 
is also the case with the current design.

However, thread1, as returned by create_thread, and the thread_ref returned 
by current_thread inside the newly spawned thread will indeed be equivalent. 
They will not only compare equal, but will be interchangeable in every way.
