The standard practice is to call Rete.runUntilHalt() in a dedicated
thread. The code below doesn't work because the event is sent just
before the activation is added to the agenda. If it -did- work, it
would be a bad idea because activations of course are often created
during a run, do you'd be calling run() recursively -- not a good
thing.
