You didn't say what platform you're running on. It works for me, using Linux
(Ubuntu 6.06):

$ ruby1.8 ert.rb 9999
Server running....
flurble                        << this sent from a client
ert.rb:16:in `accept': Interrupt
        from ert.rb:16:in `run_server'
        from ert.rb:27

If you are running Windoze, then I expect it's blocking inside one of the
socket calls.

BTW there is a fuller server example, which handles each incoming connection
in its own thread, at
