线程为什么用ps-A和pstree看不到呢

在linux下，线程是由轻量级进程实现的，我创建了一个线程，为什么用ps-A和pstree看不到呢，

void *my_function(void *arg)
{

while(1);
}

#include <pthread.h>
int main()
{
pthread_attr_t attr;
pthread_t tid;

/*初始化属性值，均设为默认值*/
pthread_attr_init(&attr);
pthread_attr_setscope(&attr, PTHREAD_SCOPE_SYSTEM);

pthread_create(&tid, &attr, (void *) my_function, NULL);

}

ps 命令：

THREAD DISPLAY
       -L           show threads, possibly with LWP and NLWP columns
       -T           show threads, possibly with SPID column
       -m           show threads after processes
       H            show threads as if they were processes
       m            show threads after processes
