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.
