Fantastic, at any rate the time is down from my initial ~4 min.!
Thank you Chris. The fgrep approach is clean and to the point; and one
more reason to love the *nix approach to handling everyday problems.
Fredrik's set|dict approach in Python above gives me one more reason to
love Python. And it is indeed fast, 5x!
Thank you all for all your help.
