Comment (by bgamari):

 Ahhh, indeed this was intentional as the patch requires
 `stats.allocated_bytes`. However, I'm not sure I agree with how we went
 about this. If stat collection is now really mandatory then either we
 should remove the ability to disable it or just make sure that we always
 collect the bits that we need.
