The `Action::last_slot_handle` field is set to a high-ish value, to disambiguate slot handles from array indices. Slot handles are opaque integers, and are just used to find a slot with that particular handle. Its exact value is irrelevant; Blender only ensures that slot handles are never reused within the same Action. This particular value was obtained by taking the 31 most significant bits of the TentHash value (Nathan's hash function) for the string "Quercus&Laksa" (Sybren's cats).
