Summary: os.environ does not support __iter__.

Initial Comment:
os.environ (on FreeBSD at least) apparently uses UserDict.
When bug 448153 was fixed, UserDict lost its __iter__ method,
and thus the environ dict became non-iterable.  os.environ
should either use IterableUserDict or, more likely, dictionary.

I can fix this easily enough with a one line change to os.py:

-        class _Environ(UserDict.UserDict):
+        class _Environ(UserDict.IterableUserDict):

The question is whether the original bug fix, 448153 was 
the right thing to do.  Are more users reasonably relying 
on UserDict being iterable or are more abusing the non-
terable form?  Which makes sense for the long run?

If you want the simple fix, please re-assign back to me.
