Actually that rather defeats the point of a non-blocking server.
You're still using up a thread, and hence haven't really gained
anything over:
(defn hello-world [request]
(Thread/sleep 1)
{:status 200
:headers {"Content-Type" "text/html"}
:body "Hello world!"})
The main advantage of a non-blocking server is that you're don't use
up a thread waiting for an event (such as the user sending data, or
some other external trigger).
