I know.  Sorry, I was trying to make the general point.

My feeling here is that the things worth fixing in point releases are 
regressions (which make us look bad relative to previous releases), and 
things that have really widespread impact, like, for example, a 
miscompilation of the Linux kernel.  I think it's overkill to try to 
look at every patch and decide whether it's safe enough and valuable 
enough to backport.  In this case, we're talking about a C++0x feature, 
which means it's used by a very small fraction of our userbase at this 
point, so it certainly doesn't seem worth it to me.

I'm not saying it would be harmful, but I want to avoid having this 
conversation every time.  Once we open the door, everyone will try to 
get through it, and it's too much work for not enough benefit.
