It's like Nat Freidman's "GNU Rope"[1] from 1998 which, if memory serves, was inspired by a tool that did the same thing in IRIX. I'd like to see this functionality built into an OS loader such that the on-disk binaries can remain unchanged (think verifying reproducible builds) but the loader will relocate code in memory to maximize locality of reference.

I'm the guy who asked Nat if he'd considered using a genetic algorithm for the optimization processing.)
