> {{GridUnsafeLru.offer(..)}} method uses atomic integer as a counter. In case of integer
overflow this method will throw {{ArrayIndexOutOfBoundsException}}.
> We should use {{abs}} to avoid this. For example, like this:
> {code}
> return lrus[U.safeAbs(addIdx.getAndIncrement()) % cnt].offer(part, addr, hash);
> {code}
