+#    has AUTOCOMMIT on and executes a statement (in this case an
+#    INSERT). Master crashes just before writing the XID event."
+
+# In this scenario, master will roll back, so slave should not execute
+# the statement, and slave should roll back later when master is
+# restarted.
+
+# However, we the master to be alive so that we are sure it replicates
+# the statement to the slave. So in the test case, we must therefore
+# not crash the master. Instead, we fake the crash by just not writing
+# the XID event to the binlog. This is done by the
+# --debug=d,do_not_write_xid flag in the .opt file.
+
+# So, unlike if the master had crashed, the master *will* execute the
+# statement. But the slave should not execute it. Hence, after the
+# first test is executed, the expected result on master is a table
+# with one row, and on slave a table with no rows.
+
+# To simulate the slave correctly, we wait until everything up to the
+# XID is replicated. We cannot sync_slave_with_master, because that
+# would wait for the transaction to end. Instead, we wait for
+# "sufficiently long time". Then we stop the slave.
