You are correct that PyDict_Merge() does not need to recompute the hashes of the keys. However, your example doesn't work because you need string keys for **kwargs. The "str" class caches its hash, so you would need a dict with a "str" subclass as keys to hit that problem.

I think that calling d.update(**kw) with kw having str-subclass keys should be very rare. I'm not sure that we should care about that.
