maybe call the param responsePort to be consistent with the code for
addOnExitListener ....

I went by the names in the Dart API documentation. They are responsePort for
addOnExitListener and port for addErrorListener. Note that the names of the
functions are also inconsistent: One has an On, the other doesn't. Leaving as
is.

-    throw new UnsupportedError("addErrorListener");
+    var msg = new List(3)
+        ..[0] = 0  // Make room for OOB message type.
+        ..[1] = _ADD_ERROR
+        ..[2] = port;
+    _sendOOB(controlPort, msg);
   }
 
   /* patch */ void removeErrorListener(SendPort port) {

Ditto comment on responsePort

-    throw new UnsupportedError("removeErrorListener");
+    var msg = new List(3)
+        ..[0] = 0  // Make room for OOB message type.
+        ..[1] = _DEL_ERROR
+        ..[2] = port;
+    _sendOOB(controlPort, msg);
   }
