I'm not sure what this has to do with conditionally defining tests, it  
seems to be about extending unittest to handle a new kind of result  
(Skip). Maybe I'm confused. When we added our extra test results  
mechanisms we started with a copy of unittest because it wasn't  
factored in a way that lets subclassing work cleanly for this kind of  
thing, and we knew that no one in Python core was interested in making  
a change to the old 2.4.x tree. (Hopefully we'll be moving up to 2.5,  
but we won't be close to the cutting edge anytime soon, such are the  
fortunes of corporate life).
