+
+Upgrade `bufout` to v1.0.0, which keeps the number of listeners on the process
+and the output streams constant regardless of how many children are spawned
+concurrently: a single shared `exit`/`SIGINT` listener is attached only while
+children are running, and every child pipes into one shared pass-through per
+destination stream.
+
+That removes the reason for the CLIs to raise `EventEmitter.defaultMaxListeners`
+to 100, so those assignments are gone and Node's default limit again applies —
+restoring the leak warning it exists to give.
