To resolve 3 strings we have to download 26 MB of data.
Getting rid of filelists seems like a bad idea because they are so
useful. Implementing them better on the other hand ...
At the moment they are stored in a sqlite database which is bzip2
compressed. The filelists DB for Fedora 18 is 26 MB compressed or 143 MB
The sqlite database just stores basically the strings as-is. There
are some structures which are better for storing strings that have a
lot of common prefixes, such as tries and suffix trees.
