+     * For nested paging we don't need pool user info nor extents at all, but we can't check for nested paging here (too early during init to get a confirmation it can be used)
+     * The default for large memory configs is a bit large for shadow paging, so I've restricted the extent maximum to 2k (2k * 16 = 32k of hyper heap)
