socketserver self.request.recv() 不会卡住吗?

服务端

import socketserver

class Mysocket(socketserver.BaseRequestHandler):
        print('启动')
        def handle(self):
                while True:
                        print(self.request.recv(1024).decode('utf-8'))
sock = socketserver.ThreadingTCPServer(('127.0.0.1', 8081), Mysocket)
sock.serve_forever()

客户端

import socket

sock = socket.socket()
sock.connect(('127.0.0.1', 8081))

sock.send('haha'.encode('utf-8'))

self.request.recv(1024).decode('utf-8')这里while一直循环，不会因为等待收到消息而卡住吗？
