  27 /** The SessionManager service provides an interface to the session manager
  28     of the desktop. A session manager keeps track of applications that are
  29     running when the desktop shuts down and starts them again in the same
  30     state they were left when the desktop starts up the next time. To be able
  31     to do this the session manager needs cooperation from applications;
  32     applications have to provide sufficient information to be started again as
  33     well as restore the state they were left in. The normal flow of operation
  34     looks like this:
  35
  36     <ol>
  37     <li>The user starts the desktop shutdown.</li>
  38     <li>The session manager informs all its connected applications
  39     about the pending shutdown.</li>
  40     <li>Each application saves its current state; while doing this it may
  41         <ul>
  42         <li>The application may request to interact with the user (e.g. to ask
  43         where to save documents). This request is necessary because at any one
  44         time only one application can interact with the user. The session manager
  45         coordinates these requests and grants every application in need of user
  46         interaction a timeslot in which it may interact with the user</li>
  47         <li>try to cancel the whole shutdown; the session manager may or may
  48         not honor that request.</li>
  49        </ul>
  50      </li>
  51      <li>After saving is done the session manager signals all applications
  52      to exit.</li>
  53      <li>Applications answer the exit message by disconnecting from the
  54      session manager.</li>
  55      <li>After all applications have exited or a reasonable timeout the
  56      session manager kills all remaining applications and finally lets the
  57      desktop shut down.</li>
  58      </ol>
