 // ownership) to BookmarkStorage. BookmarkStorage loads the bookmarks (and
 // index) in the background thread, then calls back to the BookmarkModel (on
 // the main thread) when loading is done, passing ownership back to the
 // BookmarkModel. While loading BookmarkModel does not maintain references to
 // the contents of the BookmarkLoadDetails, this ensures we don't have any
 // threading problems.
