We could use a comparison tool anyway. Baron Schwartz was pointing out
that Percona has a comparison tool for MySQL, and the amount of "drift"
and corruption that they find in a large replication cluster is
generally pretty alarming, and *always* present. While our replication
isn't as flaky as MySQL's, networks are often lossy or corrupt.
