This would work so long as pari's next_prime function *never* declares any composite number to be prime, i.e., is it true that Pari's nextprime(n) returns a number m >= n such that there are provably no primes between n+1 and m-1? Could somebody check the source/docs to see if this is the case? If so, send me a patch.
