builtins/threadsafety.po (4 new fuzzy)

• ":meth:set.update and :meth:set.union lock both objects only when the other operand is a :class:set, :class:frozenset, or :class:dict."
• ":meth:set.intersection and :meth:set.difference always try to lock all objects."
• ":meth:set.difference_update and :meth:set.intersection_update try to lock all objects one-by-one."
• ":meth:set.symmetric_difference_update only locks the arguments if it is of type :class:set, :class:frozenset, or :class:dict."

c-api/slice.po (1 new fuzzy)

• "Usable replacement for :c:func:PySlice_GetIndices. Retrieve the start, stop, and step indices from the slice object slice assuming a sequence of length length, and store the length of the slice in slicelength. Out of bounds indices are clipped in a manner consistent with the handling of normal slices. length must not be negative."

Triggered by sync with 3.14 (commit b369b74).
