9 * Description: |
|
10 * This test has two threads communicating with each other using |
|
11 * two unidirectional pipes. The primordial thread is the ping |
|
12 * thread and the other thread is the pong thread. The ping |
|
13 * thread writes "ping" to the pong thread and the pong thread |
|
14 * writes "pong" back. |
