I posted these patches here because I would love to get some feedback
on them from you guys, and they need some real-life testing. The
biggest catch with this patch is ensuring we don't leave any paccheck
files behind, as we can no longer always unlink the original file
since we use rename instead of copy.

All of these can be found on my public 'working' branch if you are
tracking my GIT repository. I'll hold off a few days before pushing
these to master.
