+# split has the following properties:
+#
+# * is not the leftmost leaf page
+# * key on the parent page is compares less than the key of the item
+#   on index 0
+# * triggering record's key also compares greater than the key on the
+#   parent page

+# the chain has the following properties:
+#
+# * record at index 0 is located where it will not get overwritten by
+#   items written to the right-hand page during the split
+# * key of the record at index 0 compares less than the key of the
+#   bug-triggering record
+
+# If the page-split bug exists, this test appears to create a database
+# where some records are inaccessible to a search, but still remain in
+# the file and are accessible by sequential traversal.  At least one
