I haven't mentioned downvotes to date, but the down votes on this is puzzling. Would the down voters care to comment as to why the comment is deemed down vote worthy? (I would think those who work/grok on memory managers do get the point.)
I didn't downvote it, but it mostly read like rambling nonsense to me, so that might be why. Maybe write it so it's clear to people who don't work on memory managers all day?
I think the idea is to differentiate between mutable and immutable data, ie. "worked on" and "final". I don't know what that would give you with regards to GC though.
