+search trees, such as for traversals or users relying on a particular order
+for their own logic. To this end, users can use 'struct rb_root_cached' to
+optimize O(logN) rb_first() calls to a simple pointer fetch avoiding
potentially expensive tree iterations. This is done at negligible runtime
overhead for maintanence; albeit larger memory footprint.
