    // WARNING: Bulk inserts sounded like a great idea and gave us a good performance improvement,

    // but (at least) one problem is still outstanding:

    // 1) Bulk inserts broke the code that sets the default ringtones on first boot

    // 2) Bulk inserts broke file based playlists in the case where the playlist is processed

    //    at the same time the files in the playlist are inserted in the database

    //   on first boot

    // These problems might be solvable by moving the logic to the media provider instead,

    // but for now we are disabling bulk inserts until we have solid fixes for these problems.
