  * don't play with this unless you benchmark!
  * decompression is not dependent on the hash function
  * the hashing function might seem strange, just believe me
  * it works ;)

  * IDX works because it is very similar to a multiplicative hash, e.g.
  * ((h * 57321 >> (3*8 - HLOG)) & (HSIZE - 1))
  * the latter is also quite fast on newer CPUs, and sligthly better
