I don't know how you define simple. In order to be able to have separate GILs you have to remove *all* sharing of objects between interpreters. And all other data structures, too. It would probably kill performance too, because currently obmalloc relies on the GIL.
Nitpick: You have to remove all sharing of *mutable* objects. One day, when we get "pure" GC with no refcounting, that will be a meaningful distinction. :)
Python already grew that feature a couple years back, but it never became mainline. Search google (I don't know the magic incantation off the top of my head), buf if I remember correctly, it wasn't a significant win if any at all. - Josiah
