Then I guess any node that did add it to its memory pool would realize it’s not new and not rebroadcast it to those who didn’t, so it won’t propagate… Although, after receiving the orphan transaction TX_b, it could re-(pay attention) to an INV with TX_a (for a short-ish time to prevent further DoS vectors)?
