In my case, there is no interrupting of a thread with resources that are
shared with other tasks, nor are there tasks synchronized to the
terminating task. To state it more accurately, my sys_thread_free()
guarantees that the _thread_ resources allocated in sys_thread_new() are
reclaimed. The scenario in which it is called is an orderly shutdown of the
terminating task.
