New submission from Andreas Kloeckner:
For tests and doctests, it is often desirable to show or verify that a certain warning occurs. Unfortunately, if the warning has been hit previously, it will not be issued again. It would be great if there were a documented, unified way to reset this 'seen' flag.
Related stackoverflow posts showing that I'm not the first person to have this need:

* https://stackoverflow.com/questions/2418570/testing-warnings-with-doctest
Neither of these has a satisfactory solution.
