>Does this mean your patch is causing a performance regression (even in release)?

In release test passed, but I assume code became slower, too -- I am doing more when adding/removing event listener. Some other types are also have slower add/removeEventListenerCallback() because they also keep track of listener objects, but V8Node till that moment did not keep track, and that was the bug...

>I'm still skeptical about this approach.  This doesn't seem like the right way of solving this problem.

I discussed it with Anton Muhin. Initially he thought I should do what all other objects are doing, that is adding/removing hidden dependency, but later suggested that approach. He believes that is better, because it avoids adding extra slot to V8Node object -- there are lot of nodes, and absolute majority of them would never have listener attached.
