    ctdb-locking: Use real-time only for actual record or DB locking
    
    Use real-time priority only for obtaining record and database locks.
    Do not open databases with real-time priority as it can cause thundering
    herd on fcntl lock while opening tdb database.  Also relinquish real-time
    priority after the lock is obtained.
