Bug description:
using ubuntu touch image 82 i see the session init consume about 10MB per minute as long as the screen is on with Mir.
running the same session with surfaceflinger only consumes 1MB per minute.
in both cases the system starts to swap heavily at some point, making
the UI unresponsive.
http://paste.ubuntu.com/6196223/ has the top output of a Mir session
after 30min, the UI just got completely unresponsive when this
snapshot was taken.
http://paste.ubuntu.com/6196332/ is the top output of a surfaceflinger
session where the screen was off for about 10min
apparently the leak only occurs while the screen is on, it seems to be
permanently there but in the case of surfaceflinger it hits less hard.
