I think there's a subtle point that was lost in the thread.  While we'll 
only need to queue one fd per MonitorState, we'll still need to deal 
with multiple fds per CharDriverState.

I think the way this would most logically work would be a push interface 
verses a pull interface so that there wasn't double queuing.  That is, 
whenever the CharDriverState gets an fd, it calls a function registered 
by the consumer of the CharDriverState.
