Comment:

 Sure - I'm building AJAX caching for a plugin, and need access to WPDB as
 early as possible. The normal `admin-ajax.php` routine fully loads WP and
 all plugins, which in this case is unnecessary (every millisecond counts).

 My use case: https://gist.github.com/mgibbs189/8345521

 * A request is made to admin-ajax.php
 * Load WPDB if it doesn't exist already
 * Using WPDB, check to see if a cached version exists...
 * If YES, output the cached version and EXIT
 * If NO, continue loading WP

 This patch will help any plugin needing to implement DB-based caching.
