I remember the RHEL hugemem patch being a big deal for lots of their customers, so a process could address the full 4GB instead of only 3GB on a 32-bit machine. If I recall correctly, upstream didn't want it (get a 64-bit machine!) but lots of paying customers clamored for it. (I personally don't have an opinion on whether it's worth bothering with).
