"Number of entries: 0" every time.

Here's a test I did today, across the same four virtual machines with
replica 2 and a fifth virtual machine as a native glusterfs client:

* "shutdown -h now" on server node 02

* On the client:
# rm -Rf linux-3.12

* wait 30 seconds, and boot up server node 02

* wait until this appears on the client:
rm: cannot remove `linux-3.12/arch/powerpc/platforms/52xx': Directory
not empty

* "heal info split-brain" and "heal info" on node 01, in full:
