1. multiple connections downloading the same file from the same mirror
just feels abusive to mirrors
2. changing out how we download things to allow multiple downloads at
the same time is in the cards
3. changing out how we download things to spawn an external process is
in the cards (for selinux's sake)
4. you can download all the files in the predownload plugin hook if you
want to prototype something.
5. torrent is never going to happen. Seriously.
