this time using a timer, which allows for monitoring the flush rate along with
statistics about the flush duration.
[~frm], I think this is what we should be doing.

>
> The FileStore background operations are ultimately executed through a
> {{ScheduledExecutorService}}. In the case this scheduling gets blocked (e.g.
> because of a deadlock or lock contention in one of its tasks) there is chance
> of repository corruption.
> To minimise potential data loss we should implement monitoring endpoints for
> the vital background operations. This would allow deployments to take action
> early in case of failures and thus minimise potential data loss and simplify
> recovery.
