* Description:
|

* This test runs in conjunction with the pipepong2 test.
|
||||
* This test creates two pipes and passes two pipe fd's
|

* to the pipepong2 test. Then this test writes "ping" to
|
||||
* to the pipepong2 test and the pipepong2 test writes "pong"
|

* back. To run this pair of tests, just invoke pipeping2.
|

* Tested areas: process creation, pipes, file descriptor

* inheritance.
