I keep my .bashrc in version control and install it on all systems where I use bash. It's not the best place for platform-specific optimizations. Those 4 lines of code aren't portable, and there isn't a single line in my .bashrc that requires root privileges. I realize the example was a proof-of-concept, but I doubt this issue is easy to solve in userland, compared to just automating it in the kernel.
