`Atomics.isLockFree(n)` is used to decide whether atomic operations of width `n` bytes compile to true lock-free CPU instructions versus a runtime-emulated lock. On a typical 64-bit V8 build, what is the most accurate statement about its result for common widths?
Atomics.isLockFree(1);
Atomics.isLockFree(2);
Atomics.isLockFree(4);
Atomics.isLockFree(8);
