 Description   

To fix BF-24031, we added a usage of synchronized_value. While a lock is needed to coordinate thread access, we can use the Client lock instead of allocating yet another lock to guard access.

We should probably create a synchronized_value like class the requires client as a parameter to get the underlying type to ensure proper access.
