What if you dispatch starting from the last iteration?

* The last iteration might be removed.
* Then the next setindex might go out of bounds, but will be adjusted
to point to the last iteration.
* The worse part is that one iteration might receive the event more than once.

Not sure if that makes sense, but might be worth a try!
