maybe, what would be the interface for the GMP user?
addr = mmap (NULL, len, PROT_WRITE, MAP_SHARED, fd, 0);
if (addr == 0) error...
mpz_export (addr, ...);
But frankly, I don't think this will make a very efficient interface,
nor syntactically particularly appealing.
A huge map will cause a system to thrash, since it cannot communicate to
the system that data is not to be reused. Plain I/O will not ask for
quite that much memory.
We need to work on raw I/O. The present functions
mpz_out_raw/mpn_inp_raw have a 32-byte limitation. And wqe lack raw I.O
