I stumbled upon a great find, Drush Cutie. What it does is takes advantage of PHP's built-in web server (PHP >= 5.4) and uses a sqlite database to get a fresh, stand-alone copy of Drupal up and running, all in about a minute. It has two aliases:
drush qd and, my personal preference,
drush cutie. Original drush command is drush core-quick-drupal.
