> 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
