    Description

      When granting the global lock in MODE_S, the locking policy switches to compatibleFirst, allowing readers to skip queued writers. However, existing readers that are waiting behind writers on the global lock are not released.

      This may result in existing readers becoming blocked when running the fsyncLock command.
