I guess what went wrong here is that it had to skip quite a few
commits, and the result isn't relevant anymore. Maybe you could improve
this by handling a:

	all runs: boot failed: can't ssh into the instance

case as bad revision? And, also, if scp times out (as it did on
912964eacb11), keep retrying instead of marking the revision as good?
