Something strange with python 2.2.1 under RedHat 8.0

[Richard Kuhns]

I can't iterate over os.environ, while a 'hand-made' dictionary works.  It
works fine with python 2.2.3 under FreeBSD 4.8. I looked through the
release notes but didn't find anything I thought applied, so I guess I'd
just like to know if this is something peculiar to my system, or is it
more wide-spread? Here's what I get:
