Hi [~appy].
The lock in MOB is trying to avoid making deleted cells live again.
If we always retain the delete markers - until they are expired - in major 
compaction like what we do now in major compaction when write lock cannot be 
acquired, the locks are not needed anymore. How do you think about this 
approach? [~jmhsieh], [~mbertozzi].
