"Hard real-time" is a constraint deriving from the physical world. I would regard "hard real-time"
as constraints of the order of O(200Hz).

If you have really fast processors, and fast garbage-collection on garbage whose magnitude you can
bound, you can maybe show that hard real-time constraints are satisfied even with
garbage-collection. And if not now, then in a couple of HW-generations' time.
