Bug 212229

Description of problem:
Let's say a mirror A has the following problem:
http://wftp.tu-chemnitz.de/pub/linux/livna/fedora/testing/6/i386/xorg-x11-drv-nvidia-1.0.9626-2.lvn6.i386.rpm:
[Errno 14] HTTP Error 404: Date: Wed, 25 Oct 2006 18:40:49 GMT
Server: Apache/2.0.52 (Red Hat)
Content-Length: 412
Content-Type: text/html; charset=iso-8859-1

Let's say that I'm updating 3 packages.

What yum does is it downloads the header of packageONE from mirror A, it sees
that it's broken. Then looks for mirrorB, to continue.

Then for package TWO, yum seeks for that package from mirror A, which it finds
broken. Then it tries Mirror B.

It would be nice to have yum automatically updates its pointer to mirror B,
rather looking each time for packages in mirror A. It wastes time. People find
yum slow afterwards. 

Version-Release number of selected component (if applicable):
yum-3.0-6

How reproducible:
Everytime

Actual results:
---> Downloading header for xorg-x11-drv-nvidia to pack into transaction set.
