  Nice paper. IIRC sometime later a further important optimization, known as biased locking[1], was added to Java locks to avoid, in the always uncontended case, the expensive CAS required to acquire the lock.

  There was a sequel to this, from different researchers, also at IBM, proposing an improvement called a tasuki lock: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.92.3010&rep=rep1&type=pdf http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.92....
