RAT5, I was at a presentation some years ago about runway utilisation. It appears that one solution to speeding up departure rates on an intersecting runway is to have a permanently displaced threshold on the landing runway (given that it is long enough not to impose landing distance penalties) - since landing, crossing traffic will transit the intersection at a much faster speed. Madrid RW33/RW36 was cited as an example. So landing short there will interfere with that process.
