How much does the progress indicator bounce back and forth?  Is it
really crazy, or fairly controlled?

For master, I suggest making progressWindow=None the default and
adapting the rest of the patch to that.  Remember that we can import
storage as a library elsewhere, and we won't always want to pass in an
interface component.  I'm thinking of anaconda-cleanup and the storage
test code here.
