+For every delta with one or two bit set, and the deltas of all three

+* If mix() is run forward or backward, at least 32 bits in a,b,c

+* If mix() is run forward, every bit of c will change between 1/3 and

+mix() was built out of 36 single-cycle latency instructions in a 
+  structure that could supported 2x parallelism, like so:
+      a -= b; 
+      a -= c; x = (c>>13);

+      c -= a; b ^= x;
+      c -= b; x = (b>>13);
+      ...
+  Unfortunately, superscalar Pentiums and Sparcs can't take advantage 
+  of that parallelism.  They've also turned some of those single-cycle
+  latency instructions into multi-cycle latency instructions.  Still,
+  this is the fastest good hash I could find.  There were about 2^^68

+About 36+6len instructions.
+
+The best hash table sizes are powers of 2.  There is no need to do

+  h = (h & hashmask(10));
+In which case, the hash table should have hashsize(10) elements.

+If you are hashing n strings (ub1 **)k, do it like this:
+  for (i=0, h=0; i<n; ++i) h = hash( k[i], len[i], h);
