I think you may be overstating the importance of making OrderedDict thread-safe. It's quite rare to be able to rely on the thread safety of a single structure, since most often your state is more complex than that and you have to use a lock anyway. The statu quo is that only experts rely on the thread-safety of list and dict, and they should be ready to reconsider if some day the guarantees change.
