+- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
+ it possible for the user to create self-referencing ordered dictionaries
+ which become permanently uncollectable GC garbage. Reinstated the Py3.1
+ approach of using weakref proxies so that reference cycles never get created
+ in the first place.

- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
encode the value with filesystem encoding and surrogateescape (instead of
utf-8 in strict mode). Patch written by David Watson.
