 * This sample test aims to check the following assertion:
 *
 * It is safe to destroy a condition variable when no thread is blocked on it.

 * The steps are:
 *  -> Some threads are waiting on a condition variable.
 *  -> A thread broadcasts and destroys immediatly the condvar,
 *     then corrupts the memory of the condvar.
 *
 * The test fails if it hangs or if an error is returned, either
 * in the wait routines or in the destroy routine.
