Addd memory demand of 1664MB
Assigned memory grew to 2624MB assigned, 2125MB demand.
Let system settle to 1044MB assigned, 428MB demand

Assigned memory grew to 2732MB assigned, 2376MB demand.
After all instances of stressapptest terminated demand dropped to 464MB
Assigned memory did not balloon down after 15 minutes.
Configured second VM to have a startup memory value to consume all of the hosts free memory.
Test VM assigned memory did not balloon down.
The dmesg log has stack traces for hung_task_timeout_secs.
The call traces are trying to add pages.
