You could put the directions map into a custom GControl or custom
GOverlay, that way you don't have to worry about openInfoWindow being
asynchronous. The div in your custom code will always be there. Don't
remove it when you've finished with it, just hide it, so that the div
continues to be accessible.
Or you could place a second map outside your main map.
Or you could do it the hard way and handle the asynchronous behaviour of
the info window. Since the div won't exist at the time that you create
the GDirections, you'll need to use new GDirections(null), wait for the
"load" event and obtain the route with .getPolyline. Then open an info
window containing a named div, wait for the info window open to complete
(a setTimeout of 1ms is sufficient) create a map in the info window
(remember to use the {size} option if you're putting anywhere other than
the first tab) obtain the zoom info with gdir.getBounds() and zoom the
map. Plot the polyline and any markers.
