Core and builtins
-----------------
+- Critical bugfix, for SF bug 840829: if cyclic garbage collection
+ happened to occur during a weakref callback for a new-style class
+ instance, subtle memory corruption was the result (in a release build;
+ in a debug build, a segfault occurred reliably very soon after).
+ This has been repaired.
+
- Added a reversed() builtin function that returns a reverse iterator
over a sequence.
