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