If I call os.environ.clear in a python program child processes still
see the cleared entries. But when I iterate over the keys like so

names =  os.environ.keys()
for k in names:
    del  os.environ[k]

then the entries are also deleted for the child processes. Where is
the difference? Is this a bug? (Observed in Python 2.5.2)

This has been fixed in the upcoming Python 2.6.
