So you have to keep the runtime as up to date as glibc?  Sounds ok :-).

Also, I don't know anyone that supports people updating kernels in linux in
any sort of commercial setting for the very reason you just gave.  Sounds
like asking for trouble.  In my experience, a  kernel upgrade is taken
pretty seriously, and not done without very good reason.  Look at CentOS,
it's on a pretty old kernel most of the time, because people in enterprise
situations prefer stability over bleeding edge features.
