control.events.on({
     activate: function() {
         map.div.style.cursor = "crosshair";
     },
     deactivate: function() {
         map.div.style.cursor = "default";
     }
});

Of course you'll be better off if you use methods like:

OpenLayers.Element.addClass(map.div, "cursor_cross");

and

OpenLayers.Element.removeClass(map.div, "cursor_cross");

And then load up a stylesheet that has something like

.cursor_cross {
     cursor: crosshair;
}

var control = new OpenLayers.Control.Measure(OpenLayers.Handler.Path, {
     displaySystemUnits: {metric: ["m"]}
});

This property (displaySystemUnits) is not marked as part of the API - so 
you may have to change your app if it changes (don't imagine it will in 
2.x).
