New submission from Martin Horcicka:
This patch makes os.environ.clear() to have the same effect as:
for name in os.environ.keys():
del os.environ[name]
I believe that most people expect the effects to be the same anyway.
The practical benefit is a simpler redefinition of the whole environment
if desired (e.g. in scripts run via sudo on unix systems).
