Can't it use ref-counted COW? Then since there is only 1 reference to the original block it may mutate it in-place else it creates new chunk with refs=1 and decrements the original count. Maybe I'm missing something but it shouldn't be that hard.
Yes, that's pretty much what I was thinking of. The question is how to implement it in terms of std.allocator -- or is that the wrong base to build ref=counted memory upon?
