This sounds like a good idea.  Would it be possible to add a "dict" 
object to the end of the ufunc structure  without bumping up the Version 
number of the C-API?  I think it would be possible, but I'm interested 
in other points of view. 

If we added the dict object then we could add the __module__ attribute 
to all ufuncs and use that in pickling.  

Then, we could add an API function that took a module name and found all 
ufuncs under that name and set their __module__ attribute correctly.
