    Description

      Currently the merge semaphore in SegmentNodeStore is by default non fair. OAK-3588 provided a config option to make it fair.

      We should change the default to fair so as to ensure writer threads never get starved.

      Eventually this change would need to be backported to branches. Further going forward OAK-4122 would replace the lock
