A little linked list of available mpz_t's is maintained.  When you
want a new one you take it from that free list, and when you're
finished with it you put it back.  The idea is to avoid doing an init
and clear every time.

(In demos/perl/GMP.xs the operative part of this is hidden in the
CREATE_MPX macro.)
