There is no need to close the server socket after each connection.  Try:

def close( this ):  #close all connections and sockets
    this.conn.close()

def process( this ):
    this.bindsock()
    while 1:
        this.acceptsock()
        this.transfer()
        this.close()


Also, take a look at the SocketServer libary.  It handles multiple 
simultaneous connections and the details of setting up and tearing down 
connections:


import threading
import SocketServer

class MyHandler(SocketServer.StreamRequestHandler):
    def handle(self):
        print 'Starting media transfer '
        openfile="XMLrecieved"+str(self.server.filenumber)+".xml"
        f = open(openfile,"wb")
        while 1:
            data = self.request.recv(1024)
            if not data: break
            f.write(data)
        f.close()
        print "Got XML file:" + openfile
        print 'Closing media transfer'
        self.server.filenumber += 1

class MyServer(SocketServer.ThreadingTCPServer):
    filenumber = 1

class MyThread(threading.Thread):
    def run(self):
        listen=2222
        server = MyServer(('',listen),MyHandler)
        server.serve_forever()

t=MyThread()
t.setDaemon(True)
t.start()
