Description of problem:
Even with yum-fastestmirror plugin installed, the revisor package download
process is very slow as it downloads packages from slow mirrors, in what appears
to be a rather random selection of mirrors. Selecting mirrors randomly is a
sub-optimal strategy as it is virtually guaranteed that with a world-wide
selection of mirrors then most mirrors will be very slow for any given user.

Version-Release number of selected component (if applicable):
2.0.4.1-2.fc7

How reproducible:
Always

Steps to Reproduce:
1. Start revisor
2. click forward until it starts processing
3. wait for the download packages stage to start
  
Actual results:
Download is very slow

Expected results:
Downloading packages should be as fast as running yum on the same machine
