There are private _PyDict_*_KnownHash functions that allow to avoid repeated hash calculation in complex operations with a dict. Proposed patch makes C implementation of OrderedDict to use these functions. It is not just an optimization, it makes some OrderedDict methods atomic (or almost atomic), that decreases a chance to desynchronize the linked list with the dict. That is why I suggest to commit the patch in 3.5.
