+  okay, that was easy enough, whats next?
+
+  say, after you call paused(), write should return false
+  until resume is called.
+
+  simple way to implement this:
+    write must return !paused
+  after pause() paused = true
+  after resume() paused = false
+
+  on resume, if !paused drain is emitted again.
+  after drain, !paused
+
+  there are lots of subtle ordering bugs in streams.
+
+  example, set !paused before emitting drain.
+
+  the stream api is stateful.
