I think the code is basically fine (i had a feeling of deja-vu, did you
take this code from some py-dev posting? just curious ...).  

However, item.run() methods currently doesn't have direct means to control 
output in case of a test failure.  What we should do, i guess, is 
to say that an explicit 'py.test.skip()' doesn't print any traceback 
(maybe controlable by some command-line argument). Instead it prints 
only the given message.  You could then extend your doctest approach 
to produce the message you want py.test to show.
