In the new test runner, the `raise Exception` thing will not actually make the test as a whole fail, but at least it will generate a lot of noise in the output, which will hopefully make someone notice it, so I guess it's better than nothing...

I'm not exactly sure what you mean. You can't simply remove the return statement, as that would make the decorator not work. I would try to make this decorator call `unittest2.skipIf`, which knows how to do the right thing. So, something like
def skipTestIfFn(expected_fn, bugnumber=None):
skip, reason = ...
return unittest2.skipIf(skip, reason)
would work (I think), but you could run into some complications as now `expected_fn` gets evaluated at decorator application time rather than during test invocation.
You can try this out for your self. Remove the exception guard, apply the decorator on a class with the condition that is false, and make sure that the tests *do* run.
But maybe we should do that as a separate patch ?
