 A common thing to do in Varnish caching/LB layers is to drop cookies that
 don't match a whitelist when forwarding requests on to application
 servers. We should avoid new cookies that aren't prefixed with
 "wordpress_" so that those rules don't have to be updated as WordPress
 adds new cookies. Instead, a generic rule that looks for "wordpress_" can
 stay in place (in addition to ones related to comments and other long-
 established WordPress cookies).

 WordPress 3.6 introduced wp-saving-post-{$post->ID}. We should change that
 to wordpress_saving_post_{$post->ID} (at the very least).

 This issue was reported to me by Joshua Strebel at Page.ly.
