Damn!! I didn't scroll down far enough from your initial message!! Same idea
I thought of but reversed bit state!!

There's a byte in each that says which one it is.

The source flings them out into a mesh network, so I may get multiple
copies.
I can discard dupes, I just need to know when I have all the "slots" full.

Initially I was thinking that I'd do a bit array, set the unused bits
to 1, the "not arrived yet bits" to 0, and then flip them to 1 as the
packets arrive. When the array ands to FF, then I'm done. Seems
simple in concept, but messy so far in C.
