Comment 3 for bug 1522248

Not to be pedantic, but if progress is "0%" then udm is telling you that it is not downloading, it is waiting for download to start. The progress meter shouldn't be displayed until there is some progress to show. That's the core bug here.

I don't particularly mind if the downloads are serialised, but when I'm already waiting for a slow download to start, it's an extra irritation when my phone tells me things that aren't true.
