michael@0:  * Description:
michael@0:  * This test has two threads communicating with each other using
michael@0:  * two unidirectional pipes.  The primordial thread is the ping
michael@0:  * thread and the other thread is the pong thread.  The ping
michael@0:  * thread writes "ping" to the pong thread and the pong thread
michael@0:  * writes "pong" back.
