So, what is the attitude of people here?   Here's my take:

1) Removing ctypeslib import

* Can break code if somebody has been doing import numpy and then using 
numpy.ctypeslib
* I'm fine with people needing to import numpy.ctypeslib to use the 
capability as long as we clearly indicate these breakages.

2&3) I think defering imports for _datasource.py is a great idea.  

4) Removing "import doc"

* This was added recently I think.  I'm not sure why it's there, but it 
might be there as part of the documentation effort.   It should be 
imported with ipython, probably, but not by default.

5) The testing code seems like a lot of duplication to save .01 seconds

6) Remove unused glob --- fine.

7 - 9)  These seem fine.


In sum:  I think 2, 3, 6, 7, 8, and 9 can be done immediately.  1) and 
4) could be O.K. but 1) does break code and 4  I'm not sure about.    5 
seems like it's too much code duplication for too little savings for my 
taste.

We need to push of the release of 1.2 I think.   We are rushing to get 
it out by SciPy and it is causing some rushing of collaboration so that 
people who would like to comment are feeling that they can't or that 
their comments are not desired or valued.  I'm sorry for what I've done 
that might have left that impression.
