So your last mail meant that you couldn't reproduce the long wait time
problem, right?

By the current code, if we write 100G and immediately shutdown the VM,
we will wait for sheep flushing 100G to the backend before it completely
turn off the VM. As above mentioned, we can mitigate this problem by
introducing background pusher, that is flushing while writing.
