title: Why is PyPy translate so slow?
body: <p>It takes hours to translate pypy implementation to c files and build the pypy-c on a modern notebook, with 2G mem and an Intel Core2 2GHz CPU.</p>
  
  <p>I know it's a cpu-intensive task, but does it have to be so slow? Is there any chance or room to reduce the computation, rearrange the computing order and cut the time to tens of minutes?</p>
