-// A class which implements an application JumpList.
-// This class encapsulates operations required for updating an application
-// JumpList:
-// * Retrieving "Most Visited" pages from HistoryService;
-// * Retrieving strings from the application resource;
-// * Adding COM objects to JumpList, etc.
-//
-// This class observes the tabs and policies of the given Profile and updates
-// the JumpList whenever a change is detected.
-//
-// Updating a JumpList requires some file operations and it is not good to
-// update it in a UI thread. To solve this problem, this class posts to a
-// runnable method when it actually updates a JumpList.
-//
-// Note. base::CancelableTaskTracker is not thread safe, so we
-// always delete JumpList on UI thread (the same thread it got constructed on).
