A console.log implementation that plays "nice" with large amounts of data. Keeps node alive until the output has flushed to screen.

console.log.js

/*
  A console.log that won't leave you hanging when node exits
 */
console.log = function(d) {
  var res = process.stdout.write(d + '\n');
  
  // this is the first time stdout got backed up
  if (!res && !process.stdout.pendingWrite) {
     process.stdout.pendingWrite = true;

     // magic sauce: keep node alive until stdout has flushed
     process.stdout.once('drain', function () {
       process.stdout.draining = false;
     });
  }
};
