> It's theoretically possible to pass an arbitrary page memory link (via LinkRowId) which might cause troubles:
>  # If pageId exceeds page memory limit, the JVM might crash
>  # If the page with this pageId was never initialized, an attempt to read will fail with an internal assertion (because lock state will be 0)
> A possibility for item ID to be invalid is already handled.
