+Tools/checkbtrees.py was strengthened in two ways:
+
+- In addition to running the _check() method on each BTree B found,
+  BTrees.check.check(B) is also run.  The check() function was written
+  after checkbtrees.py, and identifies kinds of damage B._check()
+  cannot find.
+
+- Cycles in the object graph no longer lead to unbounded output.
+  Note that preventing this requires remembering the oid of each
+  persistent object found, which increases the memory needed by the
+  script.
