I think a lock is still needed for cache misses. The dict operations (set and del) can release the GIL (as well as course as the PyObject_Call()), therefore you might end up with duplicate list links for a given key.

(and given cache misses are supposed to be much more expensive anyway, I don't think acquiring a lock there is detrimental)
