      Description

      This lock acquisition should be a collection IX, not a DB X. This will prevent elections from blocking behind other local database readers and writers. This is just a single document update and as a result shouldn't need a stronger lock. Before doing this we should check the history of this lock and see why it is so coarse grained.
