I'm drawing a series of markers on a map (using v3 of the maps api).

In v2, I had the following code:

  bounds = new GLatLngBounds();

  ... loop thru and put markers on map ...
  bounds.extend(point);
  ... end looping

  map.setCenter(bounds.getCenter());
  var level = map.getBoundsZoomLevel(bounds);
  if ( level == 1 ) 
    level = 5;
  map.setZoom(level > 6 ? 6 : level);

And that work fine to ensure that there was always an appropriate level of detail displayed on the map.

I'm trying to duplicate this functionality in v3, but the setZoom and fitBounds don't seem to be cooperating:

... loop thru and put markers on the map
  var ll = new google.maps.LatLng(p.lat,p.lng);
  bounds.extend(ll);
... end loop

var zoom = map.getZoom();
map.setZoom(zoom > 6 ? 6 : zoom);
map.fitBounds(bounds);

I've tried different permutation (moving the fitBounds before the setZoom, for example) but nothing I do with setZoom seems to affect the map. Am I missing something? Is there a way to do this?
