One could have a hybrid method: if the pointers are the same, the strings surely are, and otherwise the strings can be compared as before. Maybe a string that is detected as duplicate in the second case can be easily reduced to the deduped version from that point onwards. It would need to be tested how much that wins and loses in regards to comparison time vs. parallelism and that sort of things. -Olaf. -- Olaf 'Rhialto' Seibert -- rhialto at falu dot nl ___ Anyone who is capable of getting themselves made President should on \X/ no account be allowed to do the job. --Douglas Adams, "THGTTG"
