It uses a weak reference with the observer service, plus a dummy strong reference (via addEventListener()) to automatically manage the lifetime... When the node/document does away, so does the event listener.
This is sort of ok for notifications that fire a lot, but for notifications that fire rarely, or never, this effectively leaks a word of memory in the observer service. And then they all get touched at shudown. We've had bugs with hundreds of thousands of dead weak observers all hanging out in the observer service making shutdown take minutes. :(
For cases like the one linked to there, it really would be good to have a better option than dealing with the observer service...
