It is used in the pseudocode shown below to implement a busy-wait lock. L is an unsigned integer shared variable initialized to 0. The value of 0 corresponds to lock being available, while any non-zero value corresponds to the lock being not available. This implementation A) fails as L can overflow B) fails as L can take on a non-zero value when the lock is actually available C) works correctly but may starve some processes D) works correctly without starvation
