Here is how you do what this:

import socket, threading

class MyThread(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self)
        HOST = ''
        PORT = 50007
        self.s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        #! blocking operatioms on this socket (accept) will timeout
        self.s.settimeout(1)
        self.s.bind((HOST, PORT))
        self.s.listen(5)
        self._stop = False
    def stop(self):
        self._stop = True
    def run(self):
        while 1:
            try:
                if self._stop:
                    print "stop requested"
                    break
                conn, addr = self.s.accept()
                print "connection from", addr
            except socket.timeout:
                print "timeout"
            except socket.error:
                print "socket.error"
                break
        self.s.close()
        
def TimerFucn(t):
    print "TimerFucn"
    t.stop()
    # you can do t.close(). accept() will throw an exception 
    # in thos case all the stuff with stop() is not needed

listener = MyThread()
t = threading.Timer(10, TimerFucn, (listener,))
t.start()
listener.start()

while 1:
    s = raw_input()
    if s[0] == 'q':
        break
