Code review comment for lp:~laurynas-biveinis/percona-server/fake-changes-from-fb-5.5

start|stop_fake_changes.inc:

SELECT ROWS FROM INFORMATION_SCHEMA.INNODB_TABLE_STATS and SHOW INDEXES may cause test instabilities if there is a non-fake-change session workload for the same table running in parallel to the fake change one and the automatic stat recalculation kicks in at a wrong time. This need either ANALYZE TABLE, either disabling auto recalc. Right now the former seems like a better option IMHO.
