I hope you will include it in 3.3 though; it is great functionality. I 
would really like to see it enabled by default as well.

It seemed from the discussion that the biggest barrier to enabling it by 
default was possible difficulties when embedding Python (multiple 
interpreters, potential conflicts with application signal handling). A 
public C-API to disable the functionality per interpreter would be one 
option for this. Another possibility would be providing a C-API to 
enable it and have the Python interpreter application call this, so that 
the functionality remains off by default for embedded interpreters but 
on for normal uses.

All the best,

May you do good and not evil
May you find forgiveness for yourself and forgive others
May you share freely, never taking more than you give.
