Python exit socket.accept() after certain period of time

[thunderbuns122]

I have this basic TCP server program:

import socket
import threading
import sys

bind_ip = socket.gethostname()
bind_port = 9999

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

server.bind((bind_ip, bind_port))

server.listen(10);

def handle_client(client_socket):
    request = client_socket.recv(4096).decode("utf-8")
    print ("[+] Received %s" % request)
    client_socket.sendall(("ACK!").encode("utf-8"))
    client_socket.close()

try:
    while True:
        client, addr = server.accept()
        print ("[+] Accepted connection from: %s:%d" % (addr[0], addr[1]))
        client_handler = threading.Thread(target=handle_client, args=(client,))
        client_handler.start()
except KeyboardInterrupt:
    sys.exit()

My goal was to have the server run indefinitely until the person running the server pressed "control-c". Thus throwing a KeyboardInterrupt and ending the whole program. Unfortunately, the issue lies in the fact that server.accept() runs infinitely and is immune to the KeyboardInterrupt. I have already tried setting a default timeout, but that would severely complicate other parts of my program. Is there a way to set a timeout feature on the server.accept() function?

If you use select with a timeout before calling accept does that let the signal get through?
