Actually, I was under the impression you introduced that optimization in
1.2.0, in fact I checked, and the hashing is not being called with one
server under 1.2.0.

Here is the benchmark with 1.2.1 howerver:
Benchmarking libmemcache in c directly...
Performed 40000 sets in 2.213733 seconds.
Performed 40000 gets in 2.144761 seconds.
Performed 20000 gets of 2 values at once in 1.218654 seconds.

As you can see, the gets where slightly faster (maybe not statistically
significant though)... so maybe I'm missing something and the hash was
getting called in 1.2.0.
