out-of-core with gmp

[Mateus Teruel]

Greetings, I was wondering if it's possible to do out-of-core processing
with GMP, because I need to work with +-10GB integers in a 4GB RAM
computer, right now I'm using mpz_export to work with 1GB at a time, I
searched in the mail archive and couldn't find anyone talking about this,
sorry if I missed it. And do you have any estimated date to release the
mpz_rootexact function?

Thank you.
