It's true that the library could have been designed to rely solely on events. All operations could accept wait_lists and return either an event or a wait_list (for those algorithms with multiple outputs).

Since it wasn't done in that way (and I don't mean to imply any judgment, here; I recognize there are benefits to the current design), we're in a position of looking to plug holes in the existing design to enable full exception safety and reduce the set of usage errors that can occur.
