Hash-Flooding DOS Attacks?

Several years ago there was a flurry of activity regarding fast, lightweight, non-cryptographic hashing functions. There was CityHash, MurmurHash, and others. Aumasson and Bernstein did a careful analysis of these, and their resistance to Hash-Flooding DOS attacks, and found them all wanting. They recommended a different non-cryptographic hashing function called SIPHASH:

Does anyone know (Martin?) i f LW uses a hashing function that has inherent resistance to Hash-Flooding?
