It should completely self-destruct in 1024 N + k steps, where k is an arbitrary constant not depending on N, leaving only a single glider as output.
It might be a fun exercise to try to complete this pattern by adding SODs around the remaining circuitry and redirecting the excess gliders from the p512 faucet to clean the configuration. Note that the phases of the semi-Snarks do not depend on N, so there are no annoying phase difficulties -- just plenty of self-destructive fun!
The challenge is to do this as simply as possible, using relatively few still-lifes and restricting oneself to only the most common objects (boats, blocks, beehives, loaves). The pattern should be glider-constructible in order for it to serve its intended purpose.
