Review comment:
Adding it here, makes it a distribution config setup...For system
property you need to add in "SystemPropertyHelper". Look into
"EVICTION_SCAN_MAX_THREADS" as an example.
Also, tests to verify the system property setting are working as expected....

Review comment:
Does this needs to be before "try"? if lock throws exception without
locking we may be trying to unlock it...

> Parallel Disk Store Recovery when Cluster Restarts
> --------------------------------------------------
>
> Key: GEODE-8035
> URL: https://issues.apache.org/jira/browse/GEODE-8035
> Project: Geode
> Issue Type: Improvement
> Reporter: Jianxia Chen
> Assignee: Jianxia Chen
> Priority: Major
> Labels: GeodeCommons, GeodeOperationAPI
>
> Currently, when Geode cluster restarts, the disk store recovery is
> serialized. When all regions share the same disk store, the restart process
> is time consuming. To improve the performance, different regions can use
> different disk stores with different disk controllers. And adding parallel
> disk store recovery. This is expected to significantly reduce the time to
> restart Geode cluster.
