KeyboardInterrupt catch does not shut down the socketserver

[Igor Katson]

I have problems in getting a SocketServer to shutdown. Why does this not 
actually stop the application?

from SocketServer import UnixStreamServer, BaseRequestHandler

server = UnixStreamServer('/tmp/ss.sock', BaseRequestHandler)
try:
    server.serve_forever()
except KeyboardInterrupt:
    server.shutdown()


After that the server does not respond any more, but the application hangs.

What's the proper way to shutdown the socketserver and what is my mistake?
