Ahh, right.

We used to have postponed import hooks for that in past
but afaik we dropped these because they were hackish and at some moment 
the time of importing scipy improved (I think it was in Python 2.4 or 
2.5) considerably.

Nevertheless, the test functions could import nose only when required.
That would save some import time.
