dispatcher uses self._fileno to store socket's fd. 

    def del_channel(self, map=None):
        fd = self._fileno
        if map is None:
            map = socket_map
        if map.has_key(fd):
            #self.log_info('closing channel %d:%s' %
(fd, self))
            del map[fd]

calling close() for already closed channel will remove
new channels with same fileno.

The simple fix works perfect:

    def del_channel(self, map=None):
        if self._fileno is not None:
            fd = self._fileno
            if map is None:
                map = socket_map
            if map.has_key(fd):
                #self.log_info('closing channel %d:%s'
% (fd, self))
                del map[fd]
            self._fileno = None
