For now, I think I'd like to consider just translating the existing
scm_c_random_bignum to manipulate mpz_t values rather than the old
bignum digits.

If you (or anyone else) is familiar with this function, could you
explain the critical parts?  I can probably figure out how to
translate it eventually by just looking at the code, but that process
would probably go a lot faster if I had an overview.

I'd like to know things like how critical it is that it operate on
16-bit chunks -- what interdependencies does that create, etc.  If
possible, it'll probably be faster and easier to work with larger
chunks when manipulating the mpz_t's.

Thanks
