Message 174007 - Python tracker

This has been discussed in python-ideas two years ago (I've resurrected the thread there)

Sadly I didn't have time for this before, but as in 15 days we have a sprint on cpython at PyCon Argetina 2012, maybe it would be a good idea discuss this again.

Sorry if I've made any mistake, this is my second patch here, and my C skills are rusty as I've mentioned in the other issue.
