Nope, this was just waiting around to close a hidden mathplotlib window. How zmq being used is still a bit mysterious.
Initially suspected issue with zmq, starts 5 processes which dont take CPU and seems to hang.:

After 10 mins of seemingly hanging interrupted and then killed by closing tab:

Initially xclock and root fail to work saying:
root: can't figure out DISPLAY, set it manually
In case you run a remote ssh session, restart your ssh session with:
=========> ssh -Y
Resolved by logging out and back in again, following the XQuartz install.
This was due to the above “hang” and killing the session.

Curiously try again with some logging added and it seems to work. Order 10 “Photon hit time” matplotlib windows are popped up. Have to close them in turn for script to complete:
