      Currently, when we modify GlobalLockAcquisitionTracker:_globalLockMode, there is a possibility that the step down thread is reading its value concurrently. In order to avoid the step down thread from reading a garbage/stale value, make GlobalLockAcquisitionTracker:_globalLockMode as an AtomicWord<unsigned char>.
