Frankly weird that they were resorting to high level containers for this in the first place. Also, this line struck me as odd

jemalloc multithreaded performance is actually poor(ish) compared to other modern allocators, which makes it a weird choice. But even weirder is why they're even using an allocator in the first place compared to a va MAP_ANON | MAP_NORESERVE arena carveout approach? You can also do punning that way too, which I'm not even certain if Rust supports?
