Is gs really a newly allocated resource so you have to register
it? Or is it arleady an existing one? If it does already exist
(what I assume) you should fetch it from the resource lirst (quick
look , could be wrong).

Btw, it would help telling what exactly does not work.

And, with the extra arguments, ... you really want to 'merge'
this? I think it should be added to the args, no?
