Calling exit() and returning from a POSIX thread are two totally different

If you call exit(), then you terminate the system. If you return from a POSIX
thread, then this thread exits. The scheduler just picks up the next highest
priority ready thread. This could be the idle thread.
Ok. This makes sense. I was missing the detail about the idle thread.
However, it seems that the behavior is different between the classic API and
the POSIX API. It seems that, in the classic API, terminating a task with a
return statement also terminates the system.
Yes, a function return from a Classic API task results in a fatal error.
You must use rtems_task_delete() or rtems_task_exit() to terminate a
Classic API task.
