The gains in bus traffic reduction shown on the previous slide might not outweigh the cons of this new scheme if the lock is never held for very long by any processor. This is because once the lock is released there is a surge of traffic on the bus.

As a result, we can potentially use exponential backoff to prevent excessive traffic on bus when locks are released; however, we might be unfair to some processors here (since the most recent processor will try to acquire the lock more frequently).
