> A big drive was made in 2.0 to avoid iterators on the critical path to reduce
> garbage collection.
>
> When task hooks are used, an iterator is used for each info object to pass it
> to all hooks.
>
> As this is on the critical path when task hooks are used, the same reasoning
> should apply and the iterators be replaced with for loops.
