Comment (by MikeSchinkel):

 So attached is another way to skin this cat.

 1. Added a `WP_Post::make_instance()` method that is to be called instead
 of `new WP_Post()` except inside core.  2. Added deprecation warning if
 `new WP_Post()` is called in a theme or plugin directly.
 3. Added a `'make_post_instance'` to filter instances when `new WP_Post()`
 is called.
 4. Added a `'get_virtual_post_instance'` for when the SQL query in
 `WP_Post::get_instance()` fails to find a post in the database. This will
 allow code to retrieve the post via API and then return a valid post.

 This approach is in advance of caching.
