Description of problem:
Sometimes a file download will stop - the server seems to be gone, but yum never 
times-out.  C-c will restart the file download, but from the beginning, not from the 
current file position.  Does yum need a time-out timer?  And some smarts to continue a 
download from the current file position?

Later, after a couple of mirror 404 errors, yum dies with this error message:
