``` truncate -s 10G sparse.10G dd if=sparse.10G of=/dev/zero & sudo lockstat -P -x aggsize=4m -D 10 -H sleep 10 ``` Empirically observe vmobject average hold time decreased.

``` truncate -s 10G sparse.10G dd if=sparse.10G of=/dev/zero & sudo lockstat -P -x aggsize=4m -D 10 -H sleep 10 ``` Empirically observe vmobject average hold time decreased from milliseconds to microseconds.
