windows 下多线程执行 subporcess.Popen()，但子进程无法杀死

该文章提到的 shell=False 不起作用。

简单说明：
一个可执行文件读取配置文件（非常多）在两秒内返回结果，即便修改 _work_queue 还是会因为无法关闭相应子进程导致内存溢出。

import shlex
from concurrent.futures import ThreadPoolExecutor

class BoundedThreadPoolExecutor(ThreadPoolExecutor):

    def __init__(self, max_workers, max_waiting_tasks, *args, **kwargs):
        super().__init__(max_workers=max_workers, *args, **kwargs)
        self._work_queue = Queue(maxsize=max_waiting_tasks)


def func(conf_path):
    try:
        command = f"../some.exe -d -c {conf_path}"
        args = shlex.split(command)
        proc = subprocess.Popen(args=args, shell=False, stderr=subprocess.PIPE, stdout=subprocess.PIPE)
        stdout, stderr = proc.communicate(5)
    except subprocess.TimeoutExpired:
        logger.error(f"pid:{proc.pid} communicate timeout")
    finally:
        proc.terminate()
    return proc


def callback2kill(res):
    proc = res.result()
    os.system(f"taskkill /F /pid {proc.pid}")
    

with BoundedThreadPoolExecutor(100, 500) as executor:
    for endpoint in endpoints:
        future = executor.submit(func, endpoint)
        future.add_done_callback(callback2kill)
