It's probably not too heavy and it is common practice, but if you
prefer it you can use a single named function, like:
function createMarker(latlon,markerId) {
var marker = new google.maps.Marker({position: latlon, ... etc.
marker.myMarkerId = markerId;
google.maps.event.addListener(marker, 'click', function()
{markerClick(this)});
return marker;
}
function markerClick (clickedMarker) {
var markerId = clickedMarker.myMarkerId;
// Do something with markerId
}
In the scope of the event handler function the marker itself is the
variable 'this'.
That's similar to the map event handlers here:

Note that one single function handles events of the same type for all
maps.
