Huh!? Are you sure it gets stopped? There's nothing that you can
describe "Mir lifecycle"... It's unity-mir that handles lifecycle. The
only thing that *could* happen, but shouldn't any more, would be blocked
rendering when greeter inactive, causing events to be queued (but
non-blocking eglSwapBuffers handled exactly that). We just need to make
sure the correct expose events are delivered to unity8 and
unity8-greeter, as applicable.
