Summary: os.environ.copy() behaves differently in 2.2 vs. 2.3

Initial Comment:
Under Python 2.2.x, os.environ.copy() returns a copy of 
the os.environ object. Under Python 2.3.x, it returns 
what is really os.environ.data.copy(), which is different. 
See attached file for more information.

Sorry, this is not a bug.  The new behavior is the intended 
behavior -- copies are supposed to be independent from the 
original.  MvL made the correction in Lib/os.py 1.56.
