* This sample test aims to check the following assertion:
*
* pthread_once returns only when init routine has completed. 

* The steps are:
* -> call pthread_once (the init routine lasts for 1 second)
* -> check the init_routine executed

* The test fails if the init_routine has not been completed when pthread_once 
* returns.
