The solution already exists in Cog: primitive 188 can accept a third 
argument - the receiver, but it doesn't work if the CompiledMethod is 
quick. In this case the VM crashes. It does work with "normal" methods.

I prepared an image with a workspace in it demonstrating the bug:

If primitive 188 works reliably, then this feature can be added to the 
interpreter VM too.
