I looked into this a little.

The mpn API seems very hard to use.  Using it would mean reimplementing
many of the functions provided by GMP.

On the other hand, I see that Guile is using the mpz API.  So, maybe in
practice it is safe enough to just set custom allocation functions and
let them throw.
