<i>One last thing -- erlang runs bind once when it starts. Why does it need to listen on a TCP socket to run hello world?</i><p>My first thought: &quot;So this guy is investigating Erlang with strace, but he couldn&#x27;t be bothered to Google articles on its design!?&quot; Then I tried Googling this myself. Uh, yeah. I happen to know this stuff, even though I don&#x27;t use Erlang, but it&#x27;s not exactly easy to find packaged conveniently in one place.
