Nothing guarantees that two threads won't compute the factors from the same number. The only guarantee that this code offers is that, if the cache currently contains the factors for the requested number, these cached factors will be returned (and not factors for another number, or inconsistent data cause by a data race)
race condition 依旧存在，不过能保证的是返回的值不会因为 race 存在而有不一样的结果

注意 OneValueCache 里的操作都是 copy 的，不是直接赋值和返回值，这里的线程安全是指这个类两次初始化数据不会互相干扰，而不是只会初始化一次。
