@roguas I was set on the wrong foot by the "must handle signal" way of approaching this problem. There is a supported way in Java-land to clean up before shutdown and that is by adding a shutdown hook and that already works in babashka:

(.addShutdownHook (Runtime/getRuntime)
                  (Thread. #(prn "b")))
