Thanks. I'd like to also find the dead heads since they may share a lot
of history with whatever we end up fetching. A common way of doing
"resume" in bzr atm is to create a shared repository and then run "bzr
branch" in it. If this process gets interrupted somehow you can
currently resume simply by removing the broken branch and running the
"bzr branch" command again.
