zmq seems to be working, thank you.
Now I'm trying to write a more meaningful piece of code with zmq. 
I'll report on the results.
But about the latest version...

Actual code is:

  void run() {
         goOnSameThread(&runner);

         photon.delay(300.msecs); // <<=== fails here
     }

0.12.2 works well.
