CF,

If you don't mean to be rude, then don't be rude.  I never claimed that AIX is the most widely used or most important platform. It implements POSIX and Open Group specifications correctly, so it is a good cross-check that features are implemented portably without Linux or BSD assumptions.

This enhancement issue is not a demand that you or anyone else in the Python community volunteer to implement it. AIX is a very lucrative business and deployed in many businesses that the Python community would like to reach. Maybe you should broaden your viewpoint and think about why support for a "niche platform" could be beneficial for Python.
