-------
- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
This prevents user-created self-referencing ordered dictionaries from
becoming permanently uncollectable GC garbage. The downside is that
removing __del__ means that the internal doubly-linked list has to wait for
GC collection rather than freeing memory immediately when the refcnt drops
to zero.
- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
different internal state for small values of n. Fixed by salting the
value.
