> You could also use async programming to do the same thing in GC-free code. No? Allocations are blocking, "async programming" won't do anything. Unless you have an async dealloc which does the shunting implicitly, at which point you don't need an async dealloc, you can just have a sync one which shunts the actual dealloc and mandate a background thread. Which means now you're mandating a background thread for freeing memory. And you hope that the load is light enough that implicit thread which you've tasked with all deallocations (rather than just the ones which make sense) keeps up. > Or just use an arena that can be freed all at once. That is essentially the same thing, you now have a different allocation strategy for these, except it's a lot more limited and specific.
