Nice use of transactional memory if you have cpu cycles to burn.

Any follow-up on the question at the end, regarding the handling of copied data structures with pointers?

[RajivGuptaUCR]

The on-the-fly copying scheme handles this situation as follows. A parallel thread maintains a mapping table that indicates what has been copied into its memory. When a pointer is used, a check determines whether the object it points to has been copied or not. If not, then it is copied at that time and the mapping table is updated. If the object contains pointer fields pointing to other objects, then they will also be similarly copied when the pointers are used.
