Comment:

 Patch uploaded that adds an optional parameter to `wp_new_comment()`
 enabling callers to receive a `WP_Error` object return rather than dying.
 This follows the idiom used on `wp_insert_post()` and
 `wp_set_comment_status()` for example.

 The treatment for `check_comment_flood_db()` uses private global variables
 and is rather ugly but I cannot think of a cleaner way of maintaining
 complete backwards compatibility with filter/action order and so on.
 Suggestions for better solutions are welcome!

 With this fix, callers such as `wp-comments-post.php`, `wp-trackback.php`,
 the Ajax admin, XML-RPC and JSON APIs, JetPack and other plugins are now
 able to add comments safely and perform proper reasonable error handling.
