Detail:
  TaskWindow used to enable VSync events for each new task that was
    started.  However, it failed to disable the VSync events again
    when the task exited unless the task was the last one running.
    This meant that VSyncs would be going off for no reason at all
    slowing the machine down if you had ever started a taskwindow.
    Events are now only ever enabled when the first task is created,
    and disabled when the last task is killed.
