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