For things you don't want to scale, just make them divided by 'scale' . In my case,

var zoom = d3.behavior.zoom()
    .on("zoom",function() {
        g.attr("transform","translate("+d3.event.translate.join(",")+")scale("+d3.event.scale+")");

        g.selectAll(".mapmarker")  
        .attr("r",6/d3.event.scale)
        .attr("stroke-width",1/d3.event.scale);

});
