We built and tested this patch for Python 2.7.10 on a Linux machine (Ubuntu 14.04 LTS server, Intel Xeon – Haswell EP CPU with 18 cores, hyper-threading off, turbo off).

Hi Vamsi,

Thank you for your work and your detailed email.

I'm -1 on the idea because:

* Performance improvements are not bug fixes
* The patch doesn't make the migration process from Python 2 to Python 3 easier
* In long term, it would be nice to work on making Python 3 better:
See http://bugs.python.org/issue11549 for an example task.
