To be fair, almost all longer running applications fall into the "same stuff for long time in a loop" category. Whether it's a GUI event loop, rendering, scientific computation, or a network server. Sure, very small scripts and hooks only do one thing one time, but usually those aren't the things that benefit from being heavily optimized in the first place, and could just as well be left interpreted (even better -- as interpreted code is more compact and thus better fits in the cache). The same holds for every other JIT-based language.
