  okaay so the idea is, just after the long straight you make a series
of very tiny corrections by bringing each of the tracks inwards -
closer together - so that when you get to the point where you *have*
to be 5-7mil apart you're already neeearrrrly that far apart *anyway*
so it's not so bad.

 ok :)  that's perfectly doable.
