handle_requests继续在服务器上无限服务

Question

TCPServer。handle_request()保持与serve_forever类似的服务请求，此后生成的所有线程均不能满足新请求，

import http.server
import socketserver
import socket
import threading

class ClientThread(threading.Thread):
    def __init__(self,clientAddress,clientsocket):
        threading.Thread.__init__(self)
        self.csocket = clientsocket
        print ("New connection added: ", clientAddress)
    def run(self):
        print ("Connection from : ", clientAddress)
        #self.csocket.send(bytes("Hi, This is from Server..",'utf-8'))
        msg = ''
        while True:
            data = self.csocket.recv(2048)
            msg = data.decode()
            if msg=='exit':
              break
            print ("We will be echoing back messages to the client\n", msg)
            self.csocket.send(bytes(msg,'UTF-8'))
        print ("Client at ", clientAddress , " disconnected...")

# local host 
LOCALHOST = "127.0.0.1"
PORT = 8080

# defining our socket connection
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server.bind((LOCALHOST, PORT))
Handler = http.server.SimpleHTTPRequestHandler

print("Server started at",LOCALHOST,":",PORT)
print("Waiting for client request..")

while True:

    server.listen(1)
    clientsock, clientAddress = server.accept()
    newthread = ClientThread(clientAddress, clientsock)
    newthread.start()   

    with socketserver.TCPServer(("", PORT), Handler) as httpd:
        httpd.handle_request()
        httpd.socket.close()
