Comment 2 for bug 1304513

"allow for tearing" might not actually have tears on android. Android guarantees 'no tearing' with fences, so the only way to see a tear on the screen is to ignore the fences, and this has a nasty tendency to make internal driver resources grow and make OOM errors happen. (esp on exynos). So while we could enable the buffer queue to do something like this, we shouldn't try to tear out the fences from android.
