The sockets stays allocated and in use for some timeout period after you
close it. 
I solved this one by setting the SO_REUSEADDR option thru overridding
server_bind:

def server_bind(self):
    self.socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR,1)
    SocketServer.TCPServer.server_bind(self)
