The problem is that AFAIK it is not safe to call the allocation routines
from finalizer routines and lisp code cannot be guaranteed to be
cons-free. Not even compiled one. If you want to add finalizers, they
should be low-level C code and you can attach them using the
Boehm-Weiser routines (See alloc_2.d for an example).
