SocketServer clean shutdown from signal

[Jeffrey W. Collyer]

I'm using SocketServer.StreamRequestHandler to write a multithreaded network
daemon.  In normal useage it will serve requests forever and never shut down.
However, I want to be able to send the server a kill signal and immediately
restart it on the same port.  (this is under Unix, specifically Solaris).

I built the signal handler outside of the class, and I don't seem to be able
to cleanly release the socket when the server gets a kill.  If I have a 
client connected to the server, when I send the kill, the socket goes into
TIME_WAIT no matter what I try. 

Is there anyway around this?

I have something like this :

----

# set up signal handler
def sighandler(signum,frame):
	# my stuff here
        os._exit(0)


signal.signal(signal.SIGINT,sighandler)

class MyHandler(SocketServer.StreamRequestHandler):


def main():
        host=''                 # localhost name
        port=31752               # local port number
        # create the Threading server
        server = SocketServer.ThreadingTCPServer( (host,port), MyHandler)
        server.allow_reuse_address=1
        server.serve_forever()

----

I can't seem to access the socket object of the Myhandler instance server
inside the signal handler.  If I do a 

server.socket.close()

I get an exception.


Any ideas?
