  41  * Description:
  42  * This test runs in conjunction with the sockpong test.
  43  * This test creates a socket pair and passes one socket
  44  * to the sockpong test.  Then this test writes "ping" to
  45  * to the sockpong test and the sockpong test writes "pong"
  46  * back.  To run this pair of tests, just invoke sockping.
  47  *
  48  * Tested areas: process creation, socket pairs, file
  49  * descriptor inheritance.
