Review comment:
I had thought about using `ExecutorServiceRule`. However, the return
value of `doLockDiskStore()` is non-deterministic. I can't assert the return
value of individual thread. I can only count and assert the number of returning
values when all threads are done. I am not sure how `ExecutorServiceRule` will
serve this test case.

> 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
>
> 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.
