Pete Vine:

You may find it interesting on a 1GB, cortex-a5 board, PyPy 2.6.1 is actually 2-25% faster in a few benchmarks:                               

```
bm_mdp -> 1.0193x faster
crypto_pyaes -> 1.1196x faster
django    ->   1.0296x            
hexiom2 -> 1.2309x faster
meteor-contest -> 1.0180x faster
richards -> 1.2676x faster
spectral-norm -> 1.1051x faster
telco -> 1.1002x faster
twisted_iteration -> 1.0277x faster
```

I'd also similarly benchmarked the slow-path versions of 32-bit x86 pypies in case you're interested.
