多线程 queue 问题，求助大神

运行环境：CentOS Linux release 7.6.1810 + Python 3.6.8

以下代码在 linux 跑总是会死锁 hang 死， windows 10 下运行正常，这个怎么理解？

# coding: utf-8

import queue
import time
import _thread

class QueueTest(object):

    def __init__(self):

        self.q = queue.Queue()

    def test_function(self,num):

        while True:
            self.q.put("this is number: %s" % num)
            time.sleep(0.1)

    def producer(self):
        for i in range(1500):
            _thread.start_new_thread(self.test_function,(i,))

    def consumer(self):
        while True:
            num = self.q.get()
            print(f"get message: {num}\n")

    def print_qsize(self):
        while True:
            self.qsize = self.q.qsize()
            print(f"this queue size is {self.qsize}\n")
            time.sleep(1)

test = QueueTest()

test.producer()
for i in range(150):
    _thread.start_new_thread(test.consumer,())
test.print_qsize()
