Does the dialog module do anything similar to the htable dmq_init_sync behavior?

The scenario is restarting the offline member of an HA pair after modifying the script. We're unsure of the state of the replicated dialogs post-restart. Will the standby become aware of the dialogs prior to the restart? In other words, do we need to wait until the pre-restart calls end before we can safely failover?
