Is it a good idea to send stats while exiting and rely on the same? I
think before_shmem_exit is mostly used for the cleanup purpose so not
sure if we can rely on it for this purpose. I think we can't be sure
that in all cases we will send all stats, so maybe Vignesh's patch is
sufficient to cover the cases where we avoid losing it in cases where
we would have sent a large amount of data.
