It is already defined in the InterpreterProxy, so in principle
'interpreterProxy addGCroot: ... ' should work from a plugin. However,
I do not see any actual examples of this being used in any plugins
in my image. I have a hard time figuring out how to use something
like this without a working example, so maybe someone can provide a
pointer to a plugin that is currently using this mechanism?
