I think the problem is trying to delete an open file...

Is there any reason why the os.unlink (in Switchboard.py) below couldn't 
be done after fp.close?



    def dequeue(self, filebase):
        # Calculate the filename from the given filebase.
        filename = os.path.join(self.__whichq, filebase + '.pck')
        # Read the message object and metadata.
        fp = open(filename)
        os.unlink(filename)
        try:
            msg = cPickle.load(fp)
            data = cPickle.load(fp)
        finally:
            fp.close()
        if data.get('_parsemsg'):
            msg = email.message_from_string(msg, Message.Message)
        return msg, data
