Now that I've fixed that, I can tell that I made a
mistake related to the self-test code.  I can't figure
it out.

Many of the modules have code which look like

     from testing import Tester
     test = Tester().test
     bench = Tester().bench

As I understand it, this code is migrating to use nosetests.
Because people expect 'import numpy; numpy.test()' to work,
there will be a compatibility period where this API is
unchanged.

I found that importing 'testing' costs 0.013 seconds, which
is 10% of my current import time.  I would like to defer
the import until needed, so I rewrote the 'test' code as:

     def test(label='fast', verbose=1, extra_argv=None, doctests=False,
              coverage=False, **kwargs):
         from testing import Tester
         import numpy
         Tester(numpy).test(label, verbose, extra_argv, doctests,
                            coverage, **kwargs)


In my view there's no difference between them, but Tester().test does  
introspection to figure out the module location.  (In fact, if I  
don't pass it the module explicitly then it expects that locals() 
["__file__"] for sys._getframe(-1) will exist, which is not the case  
with my function.  The underling code should instead check for that  
variable in globals().)

I ended up with recursion errors, and I don't know why.  Any idea of  
what to do?
