Abstract: Method and apparatus for enabling continuous validation of a data structure by acquiring a first read lock for the data structure and processing the data structure under the first read lock. When the first read lock is relinquished and subsequently reacquired, the method provides for determining if a write lock was granted prior to reacquiring the first read lock. The data structure is further processed when a write lock was not granted and is revalidated when a write lock was granted.
