Control-D on Unix, Control-Z Enter on Windows, (System/exit 0)

I use Ctrl+D. But I am on Linux.

I use Ctrl-D on linux, but Ctrl-C works too, and is what I would try
first on Windows.

(System/exit 0) won't work if you're using leiningen to get your repl,
because it passes I/O through JLine and System.exit terminates the
clojure process without notifying the JLine process:

$ lein repl
user=> (System/exit 0)

Ctrl-C is a rather hard way to shutdown things. Compare to turning off
the computer without flushing the disk caches. With JLine Ctrl-D also
works on Windows.
