That's another good news. Thanks for all the work.

BTW, uwsgi master spawns both scripts well if I add two different ones. But
the output behaviour is a bit weirdy in the logs. It kind of buffers and
doesn't print anything until it kills the one that works with a "while
True". But the script actually works quite well over there. It's actually a
feature for me but if you still want to look, my ZMQ worker is more less:
