A while back, at Marius' suggestion, I reworked my original gmp bignum
implementation to allocate the mpz_t's using a double cell (which
definitely did help allocation) -- so you might want to check out the
bignum usage in numbers.c for an example.  Using a double cell meant I
didn't need to do anything to free the mpz_t memory in gc-card.c
(i.e. I just needed to mpz_clear the mpz_t).
