rtt的mpy能否多个线程同时运行多个python脚本?试了貌似不行

我创建了两个线程，每个线程启动python脚本。一个线程时可以运行，2个的话卡住不跑了
这个是main.c里面的
#include <stdint.h>
#include <stdio.h>
#include <stdlib.h>
#include <rtthread.h> 
#include <rtdevice.h>

static void test2_run(void *p)
{
 char py_cmd[] = "python test2.py ";
 msh_exec(py_cmd, rt_strlen(py_cmd));
 while(1)
 {
 // rt_kprintf("test2run ");
 rt_thread_delay(RT_TICK_PER_SECOND);
 }
} 
static void test1_run(void *p)
{
 char py_cmd[] = "python test1.py ";
 msh_exec(py_cmd, rt_strlen(py_cmd));
 while(1)
 {
 // rt_kprintf("test1run ");
 rt_thread_delay(RT_TICK_PER_SECOND/2);
 }
}

int test_thread(void)
{
    rt_err_t ret = RT_EOK;
    rt_thread_t thread1 = RT_NULL; 
    rt_thread_t thread2 = RT_NULL;

/* littleGL demo gui thread */ 
    thread2 = rt_thread_create("test2", test2_run, RT_NULL, 20480, 5, 10); 
    thread1 = rt_thread_create("test1", test1_run, RT_NULL, 20480, 6, 10); 
    if(thread1 == RT_NULL)
    {
        return RT_ERROR;
    }
    rt_thread_startup(thread1);
    if(thread2 == RT_NULL)
    {
        return RT_ERROR;
    }
    rt_thread_startup(thread2);
    return RT_EOK; 
}

int main(void)
{
 printf("hello rt-thread ");
 test_thread();
 return 0;
}

test1.py
import time

while(True):
	print("test1")
	time.sleep(1)
test2.py
import time

while(True):
	print("test2")
	time.sleep(1)
