Linux, BSD since 1990 or so.... For that matter I can do the same for dynamically linked applications at library level. The difference is that I don't have a happy point-and-click UI for it I have to go write a little bit of code and the efficiency level. The SuSE proposed patch for syscall restriction conveniently offers a way to remove the overhead.
