I have to run now, but tomorrow I'll write back on this.  I've been
tracking down locally how to integrate decorators with test
generators, there's definitely a bug there.  Matthew Brett and I
worked on it and I have  kludgy but functional solution, and an
improved @skipif that can take a function as the test condition, and
that works with test generators.

I'll get back to you tomorrow with that code, and hopefully we can
work out the details until we have a clean solution to push back into
the numpy test decorators module.
