Abstract
Highly concurrent systems use lock-coupling for tree traversal wherein only two levels (parent and current) are locked at any time. The parent lock is released as soon as successful lock is attained on the grandchild. The rename technique described here facilitates using finer grained locking and multiple path traversals by changing lock ownerships.
