How to handle the nodejs EMFILE exception without modifying ulimit?
stream = net.createConnection(port, host);

  stream.addListener('connect', function() {
    return stream.write(request);
  });
  stream.addListener('data', function(data) {
    return console.log(data);
  });
  stream.addListener('end', function() {
    stream.end();
    return callback();
  });
  stream.addListener('timeout', function() {
    stream.destroy();
    console.log("timeout");
    return callback();
  });
  stream.addListener('error', function(e) {
    console.log("this never gets called");
    return
  });

process.on('uncaughtException', function(err) {
  console.log(err);
});
