[UG] yum, urlgrabber and no_proxy environment?

Hello,
I've been poking around trying to get no_proxy working with yum on
Centos 5.2.  It appears this issue was raised 3 years ago in this
thread:
https://lists.dulug.duke.edu/pipermail/yum-devel/2005-June/001274.html

urllib was patched upstream to support no_proxy, but urlgrabber uses
urllib2 and I have not yet found a patch for it or urlgrabber to fully
support no_proxy.

I just came across a recent thread from Oct. 2008[1] that seems to say
no_proxy is still not supported by yum / urlgrabber.  What is the proper
way to disable proxies per repo if I cannot disable per domain using the
no_proxy environment variable?

The 2005 thread mentions setting "proxy=_none_" per repo to get around
the problem but this does not work in v3.2.8.

Any other ideas would be greatly appreciated.  Thank you.
