Failed to load application: cannot import name IFinishableConsumer

Replacing all references to IFinishableConsumer with IConsumer in allmydata/frontends/sftpd.py resolves the issue (at least cosmetically, no errors on startup). Probably would be a good idea to review the changes between the two modules for the long run.
