Description
The parallel compacting collector contains unused code for a "block table" that was an attempt to speed up pointer updates during compaction.  The code no longer works and should be removed.

                                    

Comments
EVALUATION

This block table code was never updated when the marking bitmap changed to separate the object start bits from the end bits and is now badly bit-rotted.  A new implementation is planned; see 6725714.
