     double hashing.  The first index will be V % M, where M is the
     size of the hashing table.  If no entry is found, iterating with

	  for unsuccessful search: (1 - N / M) ^ -1
	  for successful search:   - (N / M) ^ -1 * ln (1 - N / M)

     where N is the number of keys.

     If we now choose M to be the next prime bigger than 4 / 3 * N,

     are unlikely this is a good value.  Formulas: [Knuth, The Art of
