This is another one for which weave can be a godsend. The blitz module in 
weave can for many numeric expressions generate equivalent C++ code which 
avoids all the intermediate copies. I don't want to sound like a cheerleader 
(I'm not a developer of weave, only a  user), but weave is really amazing in 
how easily it allows you to integrate Numeric pyhton code with C snippets.

If anyone needs, I have a bunch of little examples lying around which I wrote 
when I was learning weave and which I can pass along, just drop me a  line.
