// e32test\pipe\t_pipe4.cpp

// This is very similar to User::WaitForRequest() but allows the User

// to specify multiple TRequestStatus objects to wait on. The function

// will return when the first TRequestStatus object completes.

13. In thread 2 , open read end of one of the pipe.

14. Main should show 1 stat variable updated.

15. Again call Wait for n request.

16. It shall come out as one stat is Available.

17. Close all the pipes. Destroy pipes.
