Hmm, this could be the reason for the behavior I experience recently.
Every time I update a couple of packages it fails to download all of
them. If I try again and again it works. I thought it was due to
improperly synced mirrors, but it happens far too frequently.
Just now it downloaded 4 packages. In the subsequent run four more, and
so on.
