1) bzip2 all successful build logs, move them to new location
2) Have a running log of which ports failed so it can be referenced mid-bulk
3) Change scheme to not cpdup all the parts that never change, make it RO tmpfs with a capped size, and only cpdup (or pax) the directions that need to be reverted per run.
