> TestMultiSlaveReplication->testMultiSlaveReplication failed in our local build citing
that "row" was not replicated to second peer. This is because after inserting "row", log is
rolled and we look for "row2" in both the clusters and then we check for existence of "row"
in both clusters. Meanwhile, Replication thread was sleeping for the second cluster and Row
"row2" is not present in the second cluster from the very beginning. So, the "row2" existence
check succeeds and control move on to find "row" in both clusters where it fails for the second
cluster.
