 Description   

From the current state of the docs it is not obvious that Range Deleter may not be able to progress if there are long running read operations / open cursors on the collection the deletes should be run on.

We should clarify this aspect so the effect of balancing can be more predictable for the users.

Hi dmitry.ryabtsev, thanks for filing this ticket. We could mention this behavior in the Range Deletion Performance Tuning section. Do you think that's the right place to mention this info?
