How to show/hide a MarkerCluster in google maps v3?

Question

I need to have different markers for different mapTypes, and I'm pushing them to a MarkerClusterer.

I "hide" the markers with:

cluster.set("map", null);
cluster.resetViewport();
cluster.redraw();

And "show" them with:

cluster.set("map", MAP);
cluster.resetViewport();
cluster.redraw();

The problem is that MarkerClusterer seems to not like set("map", null); it throws the error TypeError: Object #<a MarkerClusterer> has no method 'remove'. How can I show/hide them the proper way?

I fought my way into solving this by a little monkeypatching and a little hack. I'm still waiting for a clean answer, but this is a solution to my problem, so I'm also posting this:

MarkerClusterer.prototype.remove = function () {}

[..]

cluster.set("map", HIDDEN_MAP); // remove the clusterer
cluster.resetViewport();
cluster.redraw();
