Comment 1 for bug 855324

Status update: I am working with mvo to resolve this, but it requires some leg work. Reason is that S-C uses a Python pickle file to store the ratings data in, which we can't read the lens (and it would be error prone if we did).

We'll be moving the ratings state management to libdb-4.8 which is already shipping on the CD with Python bindings in the bsddb.dbmodule. The reason why we choose this is that it supports a single-write-multiple-reader architecture, making it safe to read from the lenses while the S-C is updating it. (plus the fact that it'll be really fast)
