Kinda, but it's currently the best I found.

There are some race conditions currently preventing that to work. Same reason I 
need to make sure in this test that the master cluster has all the edits when I 
kill a region server GC-style. See this code:

    // Test we actually have all the rows, we may miss some because we
    // don't have IO fencing.
    if (res.length != initialCount) {
      LOG.warn("We lost some rows on the master cluster!");
      // We don't really expect the other cluster to have more rows
      initialCount = res.length;
    }

So if I can lose rows on the master cluster, I can also lose rows on the slave 
cluster... but rows that are lost because of a lack of IO-fencing or because of 
a bug in the replication will be the same from the client perspective.

/me feels dumb

Mostly cruft
