* @remark This guys doing the oji plugin have been very unfortunate to link in this

* without any similar new operator. The object is thus created in the plugin
|

|
|
* is a good way of asking for trouble. But, they guys've been lucky, the VAC
|
|
* CRT might just handle this ok.
|
|
* However, we cannot perform this delete as we have no VAC CRT around, and
|
|
* hence we will leak this object.
