Oh, I forgot to add;

In such an overhaul it might also prove worthwile to convert
AsyncHandler to a daemon, to get it out of process to avoid gtk
threading madness (stop smiling Raphael ;-P)... Currently there's only
the google-live handler so we won't be spawning daemons left and right
anytime soon...
