 Agreed; apologies for the confusion, which has taken away from the point I
 was trying to make.

 The methods described above are not fool-proof, I believe, as they rely on
 the ```add_rewrite_rules``` call coming before **any**
 ```flush_rewrite_rules``` call. As the demo plugin (refactored version
 attached, using the method Nacin and DD32 described) shows, all it needs
 is some unintentionally keen plugin author to come along and flush the
 rules at an inopportunely early point and the rewrite rules we added are
 no longer in place.

 This additional action will make it possible to know that your rewrite
 rules are definitely in place each and every time
 ```flush_rewrite_rules``` gets called.
