Maybe. But not predictably. It will have delays, they may be small, but there is know way to know when they will come. This can be managed but it is all overhead. Manual memory management has none of that run-time overhead (but a tonne of programmer overhead)

I agree that manual memory management is much more predictable than garbage collection, I just wanted to touch on the nuances of the memory overhead of manual memory management.

Also, if the program creates lots of short-lived objects (which is often the case), a generational garbage collector would be pretty fast because it will reclaim/move a few objects rather than deallocating many objects. An arena collector or allocating on the stack might be better (and manual methods) in this scenario though.

It was my understanding that C4 doesn't do pauses.

But what is it? Where can I find out about it? A deterministic garbage collector would (a) prove me wrong and (b) be a Very Good Thing
