Comment:
1. We need a doctest to illustrate that you fixed this.
2. If you do {{{nth_prime(10^11)}}} twice it crashes hard. This is
because you've left diffptr in bad shape. I think there is now a way of
calling a function to clean up if there was a signal raised. This is part
of the cool new improvements to sig_on/sig_off.
Alternatively, just set diffptr to 0 after you free it, and anywhere else
that you use it, check if it needs to be initialized?
