If we reach 0 ref count, it means that we're already unlinked, so where do those events come from?
It's possible that an event task is still pending to be processed. Tasks don't hold ref to the XHR, but they do possibly grab it once processing starts.
This wasn't an issue before because we called remove_target_tasks immediately when ref reached 0. But gecko's CC doesn't necessarily call unlink/delete_cycle_collectable immediately when ref reaches 0, it usually delays it.
So a task could get processed between ref reaching 0 and the CC actually cleaning it.

It looks like we will need an equivalent of Gecko's `NS_IMPL_CYCLE_COLLECTING_RELEASE_WITH_LAST_RELEASE`. The problem with your patch is that if deletion happens, you're accessing a freed object. Gecko avoids that by explicitly requesting not to delete it with `shouldDelete` and does the deletion later if needed. Unfortunately, that would require Gecko interface extension.

That shouldn't be a problem since we call `remove_target_tasks` when unlinking/deleting it, which gets rid of the task, unless I'm missing something?
I mean I could call `remove_target_tasks` instead of incrementing `magic`, but it seems like pointless overhead because it will be called again anyway during unlink/delete.

What I mean is that if `This` is destroyed by `dispex_ref_decr`, then `This->magic++` operates on invalid memory. I guess that `remove_target_tasks` could work around it if you store the magic before calling `dispex_ref_decr`, but it's ugly...

Ah right, I could check for ref being 0 when processing the task and skip it then, is that fine?

Maybe, but we don't have ref value getter currently. I guess you we could hardcode `nsrefcnt` layout until the next Gecko release, I'm not sure. Let's take care of that in another MR. It would be good to move that commit closer to the end of conversion series so that we can see if there are more cases like that. Other patches look good to me.
