  MultiThreadedCompositor::destroy_compositing_threads hangs/deadlocks
  on shutdown or display reconfiguration

Bug description:
  Try revision 211 of lp:~unity-team/unity-system-compositor/toggle-
  cursor2/

  The desire was to resize all surfaces to the size of the smallest
  attached display.

  usc::WindowManager implements the mir::shell::WindowManagement
  interface. I thought it logical to implement this resizing in
  add_display. However it causes a deadlock when plugging in a second
  display, while the compositor is stopping, see this backtrace:

  I suspect Threads 8 and Thread 1 are blocking eachother.
