That's what I do. More or less - I do it by putting all the filenames as a key in a dict and the value is a list of the pkgs which own that file.

That portion takes 50s and 350M of ram on my laptop for f11 and updates.

then it take the list of files which have > 1 pkg owning them and grabs headers to sort them out.

awww but that was the most interesting part. :)
