Many JS GCs are internally multi-threaded and can handle multiple allocators. Even though JS isn't itself multi-threaded, the JIT and runtime systems now are, and they can concurrently allocate onto the heap. V8 has had to move towards this ability very gradually because of assumptions from the single-threaded world, but it's much more likely to support multi-threaded Wasm GC, should it be necessary, in the future. |
