+# TEST	test057
+# TEST	Cursor maintenance during key deletes.
+# TEST	1.  Delete a key with a cursor.  Add the key back with a regular
+# TEST	put.  Make sure the cursor can't get the new item.
+# TEST	2.  Put two cursors on one item.  Delete through one cursor,
+# TEST	check that the other sees the change.
+# TEST	3.  Same as 2, with the two cursors on a duplicate.
