+ * Function: test_insert_level2_3internal_split

+ * Purpose: Basic tests for the B-tree v2 code. This test inserts enough
+ * records to make a level 2 B-tree and then adds enough more
+ * records to force the left-most and right-most internal nodes to
+ * split and more records to force a 3->4 node split of the
+ * internal nodes.
