A method according to one embodiment may include determining if a sequence number of a first thread matches a current sequence number of a lock. If the sequence number of the first thread does not match the current sequence number, the method further includes placing the first thread into a wait queue; receiving a notification of an updated current sequence number by the first thread; determining if the sequence number of the first thread matches the updated current sequence number; acquiring the lock if the sequence number of the first thread matches the updated current sequence number; and remaining in the wait queue if the updated current sequence number does not match the sequence number of the first thread. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.
