Well, "select" is not just a drop-in replacement for "poll", although it
can serve the same function.  Without looking at the rest of the source,
you probably want something like this:

   def Run( self ):
        self._fdmap = {}
        self._PrepareSockets()
        while 1:
            fdi = select.select( self._fdmap, [], [] )[0]
            if fdi:
                self._ProcessInput( fdi[0] )
            else:
                logger.error( "select returned empty." )
