^^^^^^^^^^^^^^^^^
are you sure about that number? i just tried a
i: intersect read/lines %f1.txt read/lines %f2.txt
where f1.txt and f2.txt are both files with roughly 800000 lines
(~14mb each). took 0:02:47 on my machine (even that is still awful,
but 0:13:00 would be a magnitude even more awful ;).
