Warning -- os.environ was modified by test_packaging

Seen on x86 Tiger buildbot:
http://www.python.org/dev/buildbot/all/builders/x86%20Tiger%203.x/builds/2723/steps/test/logs/stdio

There is also a resource warning:

.../Lib/packaging/pypi/simple.py:86: ResourceWarning: unclosed <socket.socket object, fd=14, family=2, type=1, proto=6>
  return wrapped(self, *args, **kwargs)

If you don’t add the distutils2 component or our name to the nosy field, we can’t react quickly :)

I don’t know our networking code enough to track down the socket-related resource warnings; I’ll look into the os.environ issue.

A patch fixing os.environ warning for test_command_build_ext.py:

It is not enough.

The packaging modules has been removed from Python, so I close the issue.
