  desktop or other past screen contents visible before lockscreen on
  resume

Bug description:
  [Impact]

  On resume from suspend, screen contents are displayed for a brief time
  (perhaps 0.5 to 1 sec)  before the lock dialog appears.

  These screen contents are not always the desktop or open application
  beneath the lock screen. On at least one occasion, the screen showed
  content from a full-screen video that had been playing in Firefox some
  time before the computer had been suspended: neither the video nor its
  underlying tab were open anymore, so the image(s) was likely part of a
  buffer somewhere. (Needless to say, if the wrong full-screen video had
  been watched, depending on the setting, this could be a quite serious
  issue for some users).

  [Test Case]

  Suspend and resume the computer (closing the lid or using the session
  indicator).  Since this problem involves a race condition, it is not
  reliably reproducable at will.

  [Regression Potential]

  This fix unmaps windows when a suspend or shutdown event occurs:  it
  is possible that the window(s) do not get remapped when a wake event
  occurs, or the wake even does not get propagated.  This does not
  appear to occur in practice.

  [Other Info]

  The Ubuntu 14.04 LTS SRU was cherry-picked from upstream Unity where
  it has been released in the Ubuntu "Vivid Vervet" development release
  for a couple of months with no apparent regressions.
