Xoring with some constant is not necessarily good enough (it amounts to
initializing the hash calculation with a fixed secret value):

  http://www.eng.tau.ac.il/~yash/C2_039_Wool.pdf

The original Crosby and Wallach paper suggested a fancier approach using
universal hashing (i.e. with crypto primitives).  That's slower on
regular CPU's but with AES hardware showing up in recent x86's, maybe
it's the best way, if you want to stay with hash tables.
