Summary: 'os' patch to speed up import (and python startup)

Initial Comment:
This patch changes the _Environ subclass of UserDict to use dict 
instead, which avoids the import of UserDict, save 6-8ms on 
python startup with site.py (~4% improvement).

I tested this on my MacOS X box, but since this code is really only 
used in Win32, someone should test it there.

The patch is incorrect. dict has no attribute data, and subclassing from 
dict involves many more changes than just changing __setitem__/
__getitem__.
