+// A single UDP destination. This is done a lot less efficient than HTTP streaming
+// since we expect to have so few of them, which also means things are a lot simpler.
+// In particular, we run in the input's thread, so there is no backlog, which means
+// that there is no state (UDP itself is, of course, stateless).
