I was waiting for someone to mention this -- it seemed much more interesting to me. It's a real classic in the "what the hell, you can do that?" category. (Bonus points if you've done it in a language that requires "extra data" for strings, like storing the length somewhere.)

I must admit that I never actually benchmarked my implementation properly -- it might be interesting to see if there are actual trade-offs between mmap vs. copying. (I'm guessing that nothing can beat MMU support, but I think the MMU also supports copy operations, so...?)
