dhillonarvi@gmail.com: What is a practical motivation to this feature? imskr, as you volunteer, maybe you also have a use case that could explain the motivation?

@Elkin Motivation behind it is to throttle SQL_THREAD during applying binary logs on the replica in real high IO environment, when the replica is just for backup and delayed backup is not a concern.
