I think it's ok for the finalizer function to delete the environment object if it wants isn't it?
This isn't always the right thing to do but I think it is in the common case that there is a unique environment object for every finalized object. In the other common case that there is a single environment object for a set of objects (e.g., for all objects of the same 'type'), the finalizer might decrement a reference count on the environment object.
