173	* @remark This guys doing the oji plugin have been very unfortunate to link in this
174	* without any similar new operator. The object is thus created in the plugin
175	* but freed by xpcom.dll. As the plugin and mozilla have different CRTs this
176	* is a good way of asking for trouble. But, they guys've been lucky, the VAC
177	* CRT might just handle this ok.
178	* However, we cannot perform this delete as we have no VAC CRT around, and
179	* hence we will leak this object.
