[Gtk-sharp-list] What happened to garbage collection?

[Wei Weng]

In mono-doc on Gtk.TreeView.GetCursor 
(http://www.go-mono.com/docs/monodoc.ashx?tlink=6@ecma%3a1455%23TreeView%2fM%2f31), 
  in the remarks section, it says:

Remarks
The returned path must be freed with TreePath.Free.

huh? I thought all these would be taken care of by the garbage collection, 
and I don't need to worry about freeing resources anymore.

What is happening here? Can someone enlight?

Thanks
