{{{
When I run doctests on the file ell_rational_field.py, I end up with a
small file called PRIMES in the current directory. This shouldn't
happen: running doctests shouldn't produce files in a non-temporary
directory. However, I can't figure out how this file gets there. In
particular, if I delete the following doctests from the rank method,
then the file is not produced:

If I run these by hand from the command line, though, I don't see the
file PRIMES anywhere. Can someone familiar with the elliptic curves
code open a ticket, chase this down, and fix it?
