What in the hell does this patch do?  Why is it needed?  What does it 
fix/implement?  Doees this change affect any Bugzilla issues? Where is 
the Changelog?

This is what I have been trying to get you to do.  I have no idea what 
you are up to and I have NO access to IRC or other alternate forms of 
messaging/communications other than this mailing list.

Let's try to do things better in the future.
