> In current implementation, most of listeners do their work synchronously and
> return already completed futures. In that cases there's no sense to allocate
> the entire array of futures and fill it.
> Another reason for not allocating an array right away is the fact that we may
> have a big number of listeners, and allocating an array will be expensive and
> wasteful.
