Thank you for your feedback, @piotr.czapla.
I’d like to make the amount of data it prints customizable, since some probably would like it to be more terse, probably never silent, since it’d be hard to tell whether it was run or not otherwise. So probably by default it can be terse, printing the consumed/reclaimed data in a tight one or two liners, and if someone wants verbose as it is now, it’ll be so via a constructor argument.
Any other data to collect? time, duration?
