See the discussion going with Peter, and the decision we need to take
on this.

Ok, strange.

We don't do size checking nor 'wget -c'. However, the autobuild-run
script deletes 5 random tarballs at the end of each build, in order to
make sure we regularly re-download the upstream tarballs. This is a way
to detect no longer available upstream sites, tarballs that have
changed and other similar things. Maybe you were lucky and the two
offending tarballs had been deleted and re-downloaded?

I guess we'll see over time what happens. Thanks for checking!
