The last updates just now on three different machines gave me
Delta RPMs reduced 284.9 MB of updates to 281.0 MB (1.4% saved)
Delta RPMs reduced 14.3 MB of updates to 3.3 MB (76.9% saved)
 and the third had no Delta RPMs

Outside of specific instances, the first or last results are typical.  I
think it is time to say goodbye. Times are very different from what they
were when we added support.
