If I understood the OP correctly, by "sequential duplicate lines" he
means duplicates which are neighbours. The hash table approach would
remove duplicates over the whole file, AFAIU you.

I.e.

A        A
B        B
B   -->  C
C        B
B        C
C

versus

A        A
B        B
B   -->  C
C
B
C
