33 * \brief Test kernel preemption.
35 * This testcase spawns TASKS parallel threads that runs for TIME seconds. They
36 * continuously spin updating a global counter (one counter for each thread).
38 * At exit each thread checks if the others have been che chance to update
39 * their own counter. If not, it means the preemption didn't occur and the
40 * testcase returns an error message.
42 * Otherwise, if all the threads have been able to update their own counter it
43 * means preemption successfully occurs, since there is no active sleep inside
44 * each thread's implementation.
