This thread is too long already, but I think it may not be dedundant to point how how I wrote a linkage between Allegro Common Lisp and GMP, and how (I suspect) most mature Lisp systems with a deterministic garbage collector would do it. Let GMP do its own memory allocation. After Lisp has itself allocated a structure S with a pointer to a GMP-allocated object, it knows what to do: either S is used or not, determined by a garbage collection. When S is determined to be not used, mpz_clear or whatever, is called. This actually may not happen at the next garbage collection, but at the one after.
A complete Allegro coding of this is online in my generic lisp arithmetic package.
