 * Test case description: The column-store search routine used to search the
 * target leaf page even when the cursor is configured with append and we're
 * allocating a record number. That was inefficient, this test case
 * demonstrates the inefficiency.
 * Failure mode: It isn't simple to make this test case failure explicit since
