>            Reporter: Murtadha Hubail
>            Assignee: Abdullah Alamoudi
>            Priority: Critical
> Currently we wait for a dataset's IO operations in DatasetLifeCycleManager 
> (e.g. when dropping a dataset) while holding a lock on the dataset as well as 
> the DatasetLifeCycleManager itself. The lock on DatasetLifeCycleManager will 
> not be released until either some other thread requests a lock on the dataset 
> we are waiting on, or the IO operations finish. During that period, other 
> jobs trying to access DatasetLifeCycleManager will be blocked.
