PS4, Line 65: 	return -1;
nit: I would consider making the thread_run variations call dead_code() rather than just return -1, because they shouldn't be called in the first place when threads aren't enabled. (For the other stuff like cooperate and yield I think it makes sense to keep them as silent no-ops.)
