Wow, I feel like an idiot now!  I never thought to test that.  Thank you so much!

Is there any reason DNS would work in a standalone python app and when I embed the library via the C API dns stops working?  Is there a library I should import to fix that?

              d = downloadPage(url, "C:\\svntest\\gamerepo.ini")
              print "urls not setup, throw errors etc."

This is an example of how we have been using downloadPage from
twisted.web.client.  I have no problems getting the example to work when I
make a simple app or write the code into the intrepeter.  But if I use it
inside my app I get the user timeout below.

Unhandled error in Deferred:
Traceback (most recent call last):
Failure: twisted.internet.error.TimeoutError: User timeout caused connection

Am I forgetting something trivial?  The reactor is running as we use PB for
database pooling.  Can I not call downloadPage after a reactor is setup and

Calling downloadPage after is fine.  I'd take a look at DNS and
firewall settings for problems there.
