[Bug 1084686] [NEW] Updater download progress is very erratic

[Robin Sheat]

Public bug reported:

The download progress is very non-linear. I've had the downloaded amount
go from 1005MB to 988MB, back up to 1007MB then to 1004MB, and the total
changes too.

Those things are hard to show in a screenshot, but the attached shows
what should be an impossible situation.
