Wouldn't the same listener thing be possible with queues instead of
callbacks? I quite like it (the listener), and actually it looks like
the system the NeL guys put on (see docs section under But using callbacks in such a section, I fear we
could bring the game to an unstable state (launching callbacks over
callbacks over callbacks and so on until the game freezes or at least
gets severely slowed down). It's certainly doable and efficient with a
proven, extremly well designed system (see, I'm talking about Java here
;)), but anyway we would first have to wonder what advantages it would
have over a more classic queue system for us - I'd say it wouldn't
simplify things a lot.
