Real threads are great for implementing things like clojure's core.async or task systems like Intel's Threading Building Blocks. Both of these are super useful and don't work as well with processes instead of threads. I definitely agree that most programmers shouldn't be using threads directly, but they should be available as a building block for higher level abstractions.
