title: is node.js' console.log asynchronous?
body: <p>Are <code>console.log/debug/warn/error</code> in node.js asynchrounous? I mean will javascript code execution halt till the stuff is printed on screen or will it print at a later stage?</p>
  
  <p>Also, I am interested in knowing if it is possible for a console.log to NOT display anything if the statement immediately after it crashes node.</p>
