   > Having multiple actions would mean that a lock revokation between the 
actions can cause the task to fail after nuking the segments during 
determination of segments to kill from deep storage. In such a case, segments 
may not be cleaned up from deep storage.
   
   @AmatyaAvadhanula , just to clarify, the new task actions are simple read 
actions and do not need to check if the relevant segments are covered by locks 
or not. They do not need to run the SELECT statements in critical sections 
either. So locks being revoked would have no effect on the action unless the 
task itself has been killed by the Overlord.
   
   But I am not sure whether the Overlord explicitly kills a task whose locks 
have been revoked.
   And if it does, it could happen in the current implementation too.
