 How do you do this? It sounds a bit like threading, you probably
don't want to do that.

 Without going full bore curses there's no sane way to do multiline
updates, what you probably want to do is when you come out of poll()
and do the reads then choose the package which has the highest
percentage complete and use that for the display (although, obviously
the total percentage will still go up).
 Another one would be to display using the highest percentage
complete, from just the files that have read() something
"recently". But the benefits of this (don't see a single package
stopped at 99% for a while) might be outweighed by problems (too much
flickering between downloads, for the user).
