Since data is normally only RTX'ed after having been declared lost, I have (maybe prematurely) optimized for this case. So a series of RTXs without any incoming ACK will in fact occupy multiple buffers.

Maybe I just need to deal with this in my implementation and it doesn't require spec changes...
