 * This sample test aims to check the following assertion:
 *
 * When a thread other than the first thread of a process returns,
 * an implicit call to pthread_exit() is made with the returned value 
 * as a parameter.
 
 * The steps are:
 *
 * Same test as 1-2, 3-2, 4-1, but with return in place of pthread_exit.
 * The results shall be the same.
