*Describe the bug
我写了个多线程程序，想用qiling跑起来，做一些实验，但发现qiling不是用多线程的方式跑的，只展示了主线程。

目标程序的源代码

#include <stdio.h>
#include <stdlib.h>
#include <memory.h>
#include <pthread.h>

int money = 100;
int apple = 80;
int banana = 50;


void *buy_banana(void *arg)
{
        int i = (int)arg;
        if(money > banana){
                sleep(1);
                money -= banana;
                printf("\nbuy a banana ok, rest = %d\n", money);
        }
        return NULL;
}


void *buy_apple(void *arg)
{
        int i = (int)arg;
        if(money > apple){
                sleep(1);
                money -= apple;
                printf("\nbuy a apple ok, rest = %d\n", money);
        }
        return NULL;
}

int main(int argc, char *argv[])
{
        pthread_t thread1, thread2;

        pthread_create(&thread1, NULL, buy_banana, NULL);
        pthread_create(&thread2, NULL, buy_apple, NULL);

        getchar();
        return 0;
}

使用qiling跑目标程序的加载代码

if __name__ == "__main__":
    ql = Qiling([r"/home/ubuntu/qiling/awesome-mcu/test"], "/usr/arm-linux-gnueabi", multithread=True)

    ql.run()

qiling输出的结果：
